Quote context

- I was in jail once. I mean I accidentally burned down this house. It was abandoned, but still I got held back in school and I can't drive until I'm 21.

- But I'm over all of that. I'm painting and stuff. Writing. I want to be a writer. Or maybe a painter, I don't know, maybe both. I'll write a book and draw the pictures. Then maybe people will understand me. I don't know, change things.
