The 5 times Sokka forgot Toph was blind and the 2 times he didn’t.
Sokka: Zuko, stop moving! I’m trying to capture the moment. I wanted to do a painting, so we always remember the good times together.
Katara: That’s very thoughtful of you, Sokka. Wait, why did you give me Momo’s ears?
Sokka: Those are your hair loopies!
Zuko: At least you don’t look like a boarcupine! My hair is not that spiky!
Mai: I look like a man.
Suki: And why did you paint me Firebending?
Sokka: I thought it would look more exciting that way. Oh, You think you can do a better job, Momo?
