The poem opens with a single line of quoted speech, "they laughed at me," and then the speaker immediately shrinks it: "That's it. That's all they did." The tone is flat and sarcastic. Mocking is presented as if it were a small thing, but the speaker's bitterness suggests it wasn't.
The key move comes in the second line, where the laughter is called "all the encouragement I need." That's irony. The speaker means the opposite of what they say, or at least something more complicated: being laughed at was the push that kept them going. The casual "Yeap" and the short, almost deadpan sentences make it sound like a shrug, though the hurt seems to sit right underneath.
The mood is dry, wounded, and a little defiant. There's pride in having made it "until the end," but also a sense that it came at a cost. The speaker got there, yet the poem leaves us wondering whether spite is really a kind thing to be grateful for.
