I’m different that way. I mean, my second-oldest brother, Soda, who is sixteen-going-on-seventeen, never cracks a book at all, and my oldest brother, Darrel, who we call Darry, works too long and hard to be interested in a story or drawing a picture, so I’m not like them. And nobody in our gang digs movies and books the way I do. For a while there, I thought I was the only person in the world that did.
