172.70.162.18 (well, more precisely, the person who made [[Special:Diff/347189|this edit]]): you managed to make me frantically make two page moves thinking that you had removed the link that I added. See, I created [[:Category:Confusion matrices]] and added links to that on all the articles with confusion matrices. However, I thought you had reverted my edit when you removed a link to [[:Category:Comics with confusion matrices]]. So I thought I had created the category under the wrong name compared with what I added and went to move the category, until I realized you had indeed removed a link to a category that isn't used. Two page moves later (because I made a typo in the first move), I realized that the category's name was correct and that someone had earlier linked to a nonexistent category that was not mine.

:Hi. I was just trying to submit the following, and got Edit Conflicted about it. Right, then. Obviously it's too late to make my reasoning known (I thought it was an IP who had created the "Charts with Confusion Matrices", or whatever it was, who couldn't have even created the required page, but... well, talk about confusion!) but giving it here anyway...
Removed the category of something to do with "confusion charts", which might be something to do with the appearence as a cross-compare table (akin to a Punnet Square, not ''quite'' the same as a Karnaugh Map; probably has some name such as "compatability matrix", but I can't remember or find what that might be). Anyway, apparently "confusion chart/square/matrix/whatever" isn't a term in use that I've been able to find out there in the real world (also, it is probably supposed to guide one ''away'' from potential confusion, not cause it), it specifically doesn't have a wikipedia entry (or even a wikiledia redirect to another one by another name) and we don't have that category even if we invented the term ourselves. There are other examples of this form already under [[:Category:Charts]], so it's "a thing" that we might want to service with a Category (ideally more "Compatability Matrix" than that other name), but best to create the category and add the comic(s) as members rather than speculatively add spurious non-existent categories then rely on someone else to fulfil them at a later date. Even better to have a quick check to see if everyone agrees to the category title (and need, ...which I would actually tentatively support, in this case, if asked) beforehand.
:...just as a note, as I spent quite some time trying to find out if "confusion charts" were a thing (and coming up blank), so maybe this way I haven't wasted my time quite as much as just going away, or instead just offering a laconic apology for getting in the way.

::Ok, me again. It looks like someone found {{w|Confusion matrix}} after all, as a wikipage. I'd actually looked for various "confusion" things but... Perhaps typoed the search when I tried vs. "matrix"..? Maybe. Seems the most logical mistake to have made. So ignore my above objections. Still, I don't like the name ("deconfusion matrix" would be awful, yet better), and I've never known it by that name. Just left making my opinion known, now, however wrong it turns out to have been.

2952: Routine Maintenance

}}

==Explanation==
{{incomplete|Created by an ONCOMING LETHAL DUST CLOUD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic is almost certainly a reference to chapter 9 of the book {{W|The Little Prince}} by Antoine de Saint-Exupéry. On the first page the following quote can be found: ''"On the morning of his departure he put his planet in perfect order. He carefully cleaned out his active volcanoes."''

A recommended routine maintenance step for many electronics, such as desktop computer towers, is to remove the buildup of dust on a regular basis. This can help prevent the electrical components from overheating, and lengthen their lifetime. To make this job easier, safer, and cleaner, there exist {{w|Gas duster|cans}} of high-pressure gas, as depicted, which force through high-flow gas to displace the dust. (Attempting to do this with air from the lungs would be less effective, may add unintended moisture to the electronics, and could result in a face-full of dust.{{Citation needed}})

The comic suggests that a similar maintenance step is performed on the Earth itself, blowing gas into the Earth to force out the dust from its magma chambers. However, filling the atmosphere with dust would be unhealthy and fatal to living beings, so as a safety measure everyone would have to take shelter.

This may be a reference to one theory about the K-T extinction event — that a crashing meteor sent so much dust into the air that it killed off many plants and animals, including all non-avian dinosaurs, in a much wider area than that directly affected by the initial impact. Those lineages that chanced to survive the global effects must have been able to escape the worst of the disrupted ecosphere while the worst of the atmospheric effects subsided, and were then able to exploit various newly vacant (and/or changed) environmental niches. (This would include our own mammalian ancestors, and the avian dinosaurs that led to todays birds; some of them may, perhaps, have survived by already being more inclined/suited to living in burrows.) However, this dust cloud would have lasted longer than the 48 hours suggested in the comic.

The image suggests that the "routine maintenance" for Earth would involve using the {{w|Hawaii hotspot}} (possibly via its most active volcano, {{w|Kilauea}}), as the point to insert the high-pressure gas, causing volcanoes to erupt in Iceland, the {{w|Aleutian Islands}} or the {{w|Kamchatka Peninsula}}, the {{w|Andes}}, and elsewhere; the two geographically-indeterminate plumes may represent Italy and Indonesia.

The title text mentions using the can upside-down, and this freezing solid the magma chambers. Pressurized canisters of "air", as with similar aerosol sprayers, contain a propellant gas that condenses into a liquid when compressed. When the spray valve is opened, the release of pressure allows some of the liquid to evaporate and take the place of the released gases, or become some of the gas subsequently released (or all of it, if its purpose is not to spray other contents). The transition of the propellant liquid/gas from dense liquid to space-filling gas requires it to 'boil off', this process needing to pick up {{w|Enthalpy of vaporization|heat (or 'enthalpy') energy}}. Under typical operation, the cooling liquid/gas takes heat from the general mass of the can itself as it tries to attain thermal equilibrium. As a result, the can (and the expelled gases) will be cooled a little. Then (ultimately) heat will also be taken from anything touching or surrounding the slightly cooled can and its spray. This is precisely how a purposeful refrigerant acts, either as a one-time process or as a reversible cycle where re-pressurizing a suitable gas can 'release' heat (the heat/enthalpy of condensation) at the 'hot side' of a refrigerator, returning the gas in the system to liquid that it can later let boil again and cool the 'cold side' of the refrigerator.

It is not normally useful for such a can to allow the liquid propellant-in-waiting to exit the container, as it would waste its usefulness as a source of pressure once it does. But by holding the container the wrong way up (which way that is being dependent upon its design, and intended use...) the pressurized contents push the liquid out via the nozzle's stream. The now exposed propellant is now free to evaporate into the air at atmospheric pressure, typically much lower than the constraints it had within the can, after landing directly upon whatever the can was sprayed at. The resulting demand for heat energy (much more rapid than normal, and likely concentrated upon a much smaller target than the can itself represents) produces a greater localized drop in temperature and can lead to freezing nearby liquids (which may or may not be intended/useful). Of course, the total 'cooling effect' of such a can does not change, depending upon how it is (mis)used, it merely changes the extent (and lifetime) of application, and how extreme the temperature change may be within a much more limited 'liberation' of its cooling ability.

Spraying "canned air" with the can inverted is a party trick used to very quickly cool beverages, being able to bring them down from room temperature to ice cold in seconds if performed correctly.

{{w|Freeze spray|Some spray cans are designed to freeze objects}}, e.g. to help in plumbing repairs or finding overheating electronic components. Freeze spray is also used in medical applications. These require careful use to avoid unintentionally (or intentionally!) damaging exposed skin or objects that can be damaged by local temperature differences, such as glass.

Given the location of the planetary-scale dust-busting 'air canister', it may be considered confusing which 'way up' is the correct orientation, given that Earth-gravity would be pulling the contents sideways (however that changes what the nozzle ends up ejecting from the can itself). But such a large can would also have its own significant internal 'can-centric' gravity that possibly (depending upon how full of still-liquid propellant it is) exceeds that of the Moon, possibly letting all the denser liquid hold itself into the centre of the canister, even against the nearby Earth's gravity. Being significantly closer to the Earth than the Moon is, this can could also be a far greater influence upon Earth's own tides (not alluded to in the comic), making the dusting of the atmosphere or the freezing of some of its magma secondary issues to the sheltering population. But if magma froze to the extent of disrupting or disabling the {{w|Earth's magnetic field}}, this "secondary" issue could quickly become primary, even existential.

Three comics after this one [[Randall]] released [[2955: Pole Vault]], where the Earth is being punctured by the tip of a pole vaulting stick causing the Earth to burst like a ballon. That idea seems to be similar, but opposite the one from this comic. With so few days between the releases there might have been some similar thoughts behind the creation of both.

==Transcript==
:[The nozzle of a gas duster can is pointing into a hole on the Earth's surface in the Pacific Ocean around where Hawaii is located. This point is on the left side of the depicted Earth, so north America is centered on the drawing, with the top of South America visible beneath it. Greenland and Iceland and the most eastern part of Russia is the only other land visible. The trigger on the can is pressed as an arrow indicates and lines around the nozzle indicates that air is pushed out of the can. This results in dust clouds being released from at least five spots of the Earth, three of these are on the visible side of Earth and the volcanoes that erupts are visible, one only the top of the volcano can be seen and the last only the cloud can be seen. Other volcanoes could be erupting on the other side of the Earth without there being any visible clouds from this vantage point. The visible eruptions are in the Aleutian Islands or Kamchatka Peninsula, on Iceland and in the Andes. The one where the volcano can be seen is in Asia, most likely Japan, and the other where only the cloud can be seen is most likely in Europe, perhaps near the Mediterranean ocean. The can has a label with several lines of text, most of it unreadable. But there is a large label on it and a readable text below this:]
:<big>Dust-Off</big>
:Compressed air

:[Caption below the panel:]
:I know routine maintenance is important, but I hate how we all have to take shelter for 48 hours every year while they flush out the Earth's magma system for cleaning.

Brackets, also called parentheses, are typographical symbols used to delimit a section of text. Unlike most typographical symbols, brackets usually come in pairs, and the end bracket is typically the mirror image of the start bracket.

This comic shows a variety of (mostly) real bracket symbols, along with Randall's description.

{| class="wikitable"
|+Descriptions
|-
! Symbols
! Comic text
! Real use
! Explanation of the joke
|-
|( )
|Regular parentheses for setting stuff aside
|The regular curved bracket is the most commonly used in literature, and typically denotes aside remarks that are relevant to, but not part of, a sentence (for example, a clarifying explanation). It is also frequently used in mathematical expressions and programming languages as a grouping operator, to force a particular order of evaluation.
|Randall explains, accurately, that these are regular parentheses. No joke yet.
|-
|[ ]
|Square brackets (more secure)
|In literature, square brackets often denote meta-textual information, such as glosses, omissions, translator and editorial notes. In stage plays, teleplays, and screenplays, they can indicate stage directions. In mathematics, they are often used for {{w|Matrix (mathematics)|matrices}} or {{w|Interval (mathematics)|closed intervals}}. Sometimes they are used as outer parentheses for easier visual matching in complicated expressions. In programming languages, square brackets are commonly used as the indexing operator, with the index being placed inside the brackets. They may also be used to denote specific data structures such as arrays or lists. In language definition syntax (such as [https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form EBNF]) square brackets indicate something optional.
|The straight edges and sharper corners make these brackets resemble a solid box, presumably made of a hard material, which would be a more secure container than the "soft"-looking curved brackets. They also resemble staples, which are used to hold things in place securely.
|-
|{ }
|This stuff is expensive so be careful with it
|Known as "curly brackets." Rarely used in normal text, although may be used in expanded form to 'enclose' multiple optional lines following/preceding a single element of common purpose (similar to the 'split and recombined tracks' of [[2243: Star Wars Spoiler Generator]]). In mathematics, usually used to denote {{w|Set (mathematics)|sets}}, but other usage is possible. In programming languages most often used to denote begin and end of a separate block of code, declaring and [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer initializing objects], and other uses. In language definition syntax, it is often used to represent a set of repeated expressions.
|Curly brackets look fancy, like gates with ornate ironwork. Randall implies a world where expensive stuff is set aside using the fanciest brackets available.
|-
|‶ ‶
|Someone is talking
|Used to denote speech or citations in normal text. There are various styles from the identical pairing " " to the 66-and-99-like “ ” which differentiates opening and closing quotes. The comic appears to use a handwriting-only slope-variation.
The straight (ASCII) style is commonly used in programming languages to denote text that is data, rather than code, such as literal messages intended to be displayed to the user.

Word processors commonly implement “smart quotes” by detecting the use of the single-type keyboard character at each end of a possible quote and converting it into the fancier left/right versions (though this is not always desired, leading to the default behaviour being disabled or reverted).
|Typical form of quotation marks. Quotation marks are most often used in literature to mark dialogue (words said by characters talking) as opposed to descriptions or narrative. Some languages or communities use different typographical conventions such as „German quotation marks“. See also below for British and French conventions.
|-
|‵ ‵
|Someone British is talking
|[https://www.grammarly.com/blog/single-vs-double-quotes/ Allegedly 'British quotation marks'], although this may be disputed by actual Brits who were taught otherwise. Single quotes might be more often used as '{{w|scare quotes}}' or a related form of 'emphasis' marker. One possible distinction is that single-quotes give non-literal paraphrasing, wherever double-quotes are used for the verbatim reporting of words (spoken or written).

Often programming languages use the "..." version to denote non-program string data. In the Pascal family of languages, for example, <nowiki>''</nowiki>s indicate character-class data, with ""s being string-class data (as an inbuilt shortcut to a character-array record). As with the prior double-quotes, the comic versions appear to be handwriting-specific, with no easy-to-use equivalents in commonly used computer fonts.
|Alternative form of quotation marks. Some British media use these to mark dialogue, for historic reasons, though in modern usage the double quotes may be more common [https://www.sussex.ac.uk/informatics/punctuation/quotes/marks and acceptable].

Single quotes within double quotes (and/or double quotes within single, as necessary) can also be used to more clearly indicate reported words as part of an outer quote, i.e. when you're quoting one person and their statement contains a quote of someone else. The main quotation would be surrounded with double quotes, while the nested quotation is delimited with single quotes (or vice-versa, depending upon the house style in use). This may even be further alternated to arbitrary depth!
|-

|An Animorph is talking
|{{w|Bracket#Angle_brackets|Angle brackets}}. Aside from telepathic speech in prose, it's often used in comics to indicate that a character is speaking a foreign language that has been translated for the reader's benefit – at least notionally. Angle brackets are heavily used in [https://en.wikipedia.org/wiki/HTML HTML] as markup tags to define how the source of websites intends to convey various stylistic and/or semantic distinctions.
|Books like the series {{w|Animorphs}} or science fiction novels use these when a character is communicating nonverbally, for example via telepathy. In the ''Animorphs'' series, this is called [https://animorphs.fandom.com/wiki/Thought-speak thought-speak], or sometimes "thought speech".

|A French Animorph is talking
|French quotation marks. Used for quotes within quotes in some languages. For quoting conventions in different languages, see [https://op.europa.eu/en/web/eu-vocabularies/formex/physical-specifications/character-encoding/use-of-quotation-marks-in-the-different-languages this document].
|These symbols are French quotation marks - that's their actual name - and are used in French texts as the first-level quotes. Here Randall is mixing the SF convention described above with actual French use.
|-
|<nowiki>|</nowiki> |
|I'm scared of negative numbers but these sigils will protect me
|Vertical bars in mathematics are used for the [https://en.wikipedia.org/wiki/Absolute_value Absolute Value function].
|The absolute value of a number is its value with all negative and positive signs stripped off; in practical terms this is used to ensure a given value is positive (ex. <nowiki>|-69| = 69</nowiki>). If for whatever reason you need to "protect" your equations from negative numbers (which does come up in programming from time to time) the absolute value function has you covered — though it may not always be denoted with vertical bars. {{w|Sigil}}s are symbols used in magic, often for protection from evil.
|-
|* * _ _ / /
|I have a favorite monospaced font
|These symbols are conventionally used in text-based computer communications (such as emails, chats, Usenet News articles) to denote *bold*, _underlined_, or /italic/ font; some client programs interpret them and display actual bold text etc.
|The kind of person who uses these symbols is the kind of person who uses a {{w|terminal emulator}}, which allows users to select one's favorite (preferably monospace) font. And a {{w|Monospace font}} is a font (set of shapes used for letters, numbers and symbols) in which every character has the same width, unlike {{w|Typeface#Proportional_font|variable-width (proportional) font}}, in which the letter I is much narrower than W. While proportional font is more pleasant to read, monospace is easier to represent in simple mechanical or electronic devices, and has been used almost exclusively in the advent of computer technology, specifically in text-only environments such as {{w|computer terminals}}; these most often had only one bare-bones font that did not provide separate glyphs for different styles of character (weight, slant) or the ability to superimpose characters (directly adding underlines).
|-
|~~
|I'm being sarcastic and I had a Tumblr account in 2014
|Used in the markdown specification ([https://www.markdownguide.org/extended-syntax/#strikethrough]) to denote text with a horizontal line through it, known as "strikethrough". Used by most places that implement the markdown spec, such as Discord, Reddit, most wikis, Github, and Tumblr.
|Strikethrough markup can be found on sites like Tumblr, Reddit, or Discord to indicate that you didn't really mean something you said, and such usage peaked in the mid-2010s. This could also reference the trend of putting tildes after words or sentences to indicate the words are being said in a lilting or sing-song manner, or to indicate it is being said in a cute, nice, seductive timbre or as a particular part of a subcultural reference, e.g. in {{w|Furry fandom}}. Applied to a chosen username, it may be made to make it stand out, or else add sufficiently uniqueness despite the core name being likely to be in common use.

|The square brackets denote a mutable [https://docs.python.org/3/tutorial/introduction.html#lists list], the round brackets an immutable [https://docs.python.org/3/tutorial/datastructures.html#tuples-and-sequences tuple] , and the curly brackets a [https://docs.python.org/3/tutorial/datastructures.html#sets set]. It is valid to have them nested like this. [] could also be a slice (a bit of a list or tuple) and {} could be a [https://docs.python.org/3/tutorial/datastructures.html#dictionaries dictionary], but the syntax is wrong for these.

|Mathematical symbols meaning "floor" (i.e. round down to the nearest lower integer).
|Mathematicians stereotypically prefer to work with abstract symbols and concepts rather than numbers or indeed anything that might pertain to the real world. When presented with an actual number, it is possible that a mathematician may wish for it to be rounded to the nearest integer so that they can treat it as part of [https://en.wikipedia.org/wiki/Number_theory number theory] rather than anything to do with reality.

|Why are you trying to read my violin?
|∫ looks like the {{w|Integral symbol}} which itself is derived from a {{w|Long s}}. In mathematics it is usually paired with the differential of the variable of integration (e.g., dx). A reverse integral symbol is not used in Western mathematics typesetting; it occasionally appears in mathematical texts written in Arabic, along with other symbols likewise adapted to Arabic's right-to-left writing direction. The symbol also looks like a lowercase {{w|Esh (letter)|esh}} (ʃ), used in phonetic transcription.

There is no unicode symbol for the reversed version - it is displayed here as a reversed ∫. The esh symbol has a reversed counterpart in Unicode, but it's quite a bit shorter (ʅ).
|Violins are known for their characteristic {{w|F-hole}}s. This symbol also resembles half a pair  of curly braces.

|This {{w|Bra–ket notation|notation is used in quantum mechanics}} to notate a vector. This is called a ket, and the mirrored sign <nowiki>⟨|</nowiki> is called a bra. Combining them as bra-ket gives the inner product <nowiki>⟨|⟩</nowiki>.
| This is paraphrasing "Fear and Loathing in Las Vegas" where Johnny Depp's character Raoul Duke says: "We can't stop here, this is bat country!" while wasted on drugs, though not as wasted as later in the movie.

The title text includes different kinds of quotes, including the ASCII " and ', and Unicode “ ” (which have both an opening and closing version).
By default, iOS uses the latter curly quotes, while Windows uses the former straight quotes. Editing the same text on both an iPhone and a Windows computer can leave both types of quotes in the text.

Parentheses are a running joke on XKCD. Previous parenthetical comics include:
* [[312: With Apologies to Robert Frost]] - the punchline is a close parenthesis
* [[859:_(]] - which has an open parenthesis with none to close it
* [[1052: Every Major's Terrible]] - making fun of Computer Science as a major for its tedious use of matching parentheses

I'm British, ex 60+ years and I'm sure I was taught in school to use "for first person speech" and 'for quoting others'. I hadn't even noticed printers doing the opposite. But there again I didn't go to Grammar School. [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 07:36, 4 July 2024 (UTC)
:I'm British, too, and as I recall my school says sixty years ago, the symbols () are just called brackets and parenthesis is just the grammatical construct in which they can be used. But you can use dashes or even commas to indicate a parenthesis.

:Yeah - I don't know where this weird idea that British people use single quotes comes from - it's not my experience. Generally seems to be double quotes for direct speech, and single quotes for paraphrasing, scare quotes, 'jargonisms', etc. I've added to the explanation to reflect that a bit.[[Special:Contributions/172.69.195.176|172.69.195.176]] 11:33, 4 July 2024 (UTC)
::Similar vintage of Brit, here. Always taught to write "66s and 99s" on any primary quotation (you'd '6 and 9' quotes-within-quotes and 66/99 quotes-within-quotes-within-quotes). Except books often seemed to be single(-double(-single))-nesting, always assumed that was the US standard, as they tended to have the likes of "color" and "sulfur", too.
::In typing (typewriter, word processor and on into the internet age) I'd use ""s as my primary, unless it 'wasn't really speech'... essentially scare-quotes, or emphasis. Though in the text-only information age (usenet, etc), I'd use some of the others for /Italics/, *Bold* and _Underline_ purposes.
::For coding purposes, I'd have to use whatever the programming language required (I added the note about Pascal's character/string differentation), except in Perl, where I go for a 'sensible' mix of aesthetics/readability and practicality as I make wide use of the [https://perldoc.perl.org/perlop#Quote-Like-Operators full range of options] available to me, in quotation context, whatever doesn't clash badly with any use of q[array], qq{sub or hash}, qx|binary OR|, =~s/whatever is in my/regexp/, etc...

The integral sign (and its reverse) in the context of string instruments are the so-called 'F-holes', and they're not just decorative elements but help in the instrument(s) resonate more freely. Other shapes exist as well. See [https://en.wikipedia.org/wiki/Sound_hole here] for an in-depth explanation. [[Special:Contributions/172.69.151.27|172.69.151.27]] 09:13, 4 July 2024 (UTC)

The 'violin' quotes may look similar (but not identical) to the S-Shaped bag delimiters (U+27C5 & U+27C6), though these are normally used in the opposite order to enclose multisets.
[[Special:Contributions/172.71.90.10|172.71.90.10]] 13:52, 4 July 2024 (UTC)

The French quotation marks « » are better known as guillemets. They are also used in Spanish, and probably several other written languages. [[Special:Contributions/172.71.142.167|172.71.142.167]] 15:10, 4 July 2024 (UTC)

The single-/double-quotes being recursively embedded with the other reminds me of a short story I once read. It had the form of a tale a person was telling of when he encountered a stranger with a tale of his own. In that tale, the stranger made the aquaintance of a particularly talkative individual. That individual reported the story he heard from a further interlocutor, that story featuring the reminiscences of someone else... ''Which came to a conclusion." ...is the way it ended.' ...and so went that story" ...but of course that was just what was heard.' ...if, of course, you could credit it."'' (It was more layers deep, of course, and with both starting quotes and the paragraph-maintaining standards of opening quotes, which yet still managed to suck you in.) Cannot remember who it was by/what it was called, but obviously the play on the style (a bit more clever than ''just'' "I met a man who said, 'I met a man who said, "I met a man who said, 'I met a man who said "..."'"'") made a big impression on me at the time.

'''"~~ I'm being sarcastic and..."''' The symbol ≈ means approximately equal to. This is much used in some engineering writing. "Output level should be ≈1 Volt." In casual work this may be approximated as "~", or "~~" which is less liable to be confused for a negative sign. {{unsigned|PRR|04:02(+:03), 5 July 2024}}
:It can also be used for such as "~240V", AC power supply, and I use tildes an awful lot in Perl for both regexp operations and bitwise negation (though I also like it as a nicely distinctive choice of delimiter character for joined/split data transportation, at times) . As to the comic text, I sort of associate it with the 'decorated' usernames (akin to Dwarf Fortress 'item quality modifiers', but of course not inspired by such, not sure if they inspired it) along the lines of <code>.~·«wIeRdLyReNdErEdNaMe»·~.</code> [[Special:Contributions/172.70.91.158|172.70.91.158]] 10:21, 5 July 2024 (UTC)

:when ever I feel isolated from society, I like to contemplate the ladders I could build for them to see things from my perspective. We will never manage to teach kids how to exist in chaos, we need to outsource our thinking, share ideas, to see new options for each of the impossible answers.

It's been over five years, so I think I should be that one annoying person who breaks unspoken streaks:
If an endless ocean were a representation of life, I'd be the one who's fasioned myself an oar (or I can just use my hands to paddle if I can't get an oar). I then tell the floating people around me, "May the waves bring you luck." I proceed to go toward a location on the horizon that appears arbitrary but is actually something really cool, and then I greet all the other people who have chosen to go here also or were brought by fate/the sea (basically synonymous). Finally, I do cool things. Anyway, this comments section has been very inactive. No purpose, just wanted to motivate y'all to set goals for yourself and let you know that good things will happen if you do. For now, though, it's night, and the others are asleep in their barrels.

Working theory: this IS Beret Guy. This is I think years before his first appearance, and Beret Guy is apparently younger than anyone else who isn't explicitly a child. So this is him. The youngest form of the one who had nothing but wonder...
That DOES kind of make sense. The part where he rides the winged ferret is just the kind of weird Beret Guy thing that Beret Guy does. :)
