Travis is reading Wonder after school. The thing is, because of the way my face is, people who don't know me very well don't always get that I'm smiling. My mouth doesn't go up at the corners the way other people's mouths do. It just goes straight across my face. But somehow Jack Will got that I had smiled at him. And he smiled back.

He is not sure that he understands what he is reading.
