Faces change at the moment the poem opens: "their eyes dimmed." We never learn what the speaker has said or done to cause it, and the poem refuses to explain. What matters is the audience's reaction and what the speaker concludes from it. Judging by the imagery, the speaker has revealed something about who they are or have become, and the people around them are waiting for the "real" person to return. The central idea is a refusal of that waiting. The speaker will not be treated as a disguise, and has stopped trusting the comfort people offer.
The reactions are drawn quickly and without names: "one cried while the other huffed and another just kept staring." Tears, an irritated breath, a blank gaze. That is grief, annoyance and incomprehension in a single sentence. The onomatopoeic "huffed" makes the second reaction almost audible, while "kept staring" stretches out in time, as if the silence is the longest part. Because these people are only "one," "the other" and "another," they blur together, and that anonymity matters later.
The most striking image is the "Sooby-Doo mask." Anyone who knows the cartoon's formula knows its ending: the monster is pulled apart to expose an ordinary person underneath. The speaker imagines the onlookers staring "like waiting for" that moment, certain that what they see now is a costume and that the familiar face is underneath. The tone is wry and a little tired, since reducing a serious moment to a children's cartoon is a way of showing how unserious the others' expectation is. The next lines, "maybe two or three more times / before i'm back to being me," can be read as the speaker mimicking the onlookers' hopeful arithmetic, a phase that will pass after a few more tugs. That is an inference, because the lines do not say whose voice we hear. The ambiguity is useful, though. It lets the speaker half agree with the assumption in order to knock it down.
The knocking down comes with the lone word "but," set on a line by itself. It acts as a hinge, and the white space around it is a pause before the speaker's mood changes. The poem has no rhyme, no punctuation and no capital letters, and "i'm" stays lowercase. The effect is a voice that is speaking rather than composing, though the line breaks are precise. The first stanza runs on with its chain of "and" and "while." The second is clipped into short lines, and the shift from scene to statement feels like a door closing.
That statement begins as a question, "when will people finally understand," and the word "finally" carries real exhaustion, because this has been explained before. What follows is blunt: "promises are just empty words / and all of them were just / temporary fill-ins." The repeated "just" shrinks everything it touches, and it echoes the earlier "just kept staring." "Empty" and "fill-in" also pull against each other. A promise is supposed to fill the future with something solid, but here it only occupies space until something real arrives. "All of them" is ambiguous in a productive way. It may mean all the promises, or it may mean all the people who made them, and the anonymous "one," "the other" and "another" make the second reading plausible. If so, the onlookers are themselves temporary fill-ins.
The title and the line in guillemets, "Ya Thought Wrong," frame all of this. An "ancient artifact" is something preserved behind glass, looked at and assumed to belong to the past. The speaker may be rejecting that role: they are not a relic of the person everyone remembers, and not an exhibit to be restored. The slangy "Ya" gives the rebuttal a swagger the quiet lines never state outright.
What makes the poem worth reading is how much it does in so few lines. It gives a recognizable situation, being told "you'll go back to normal," and answers it with an image from childhood television and a bitter, plain-spoken judgment. It does not ask for sympathy. It simply declines to wait for the mask to come off.
