As answered by a fellow teacher -- text copied from enotes.com:
Kenny Watson is the protagonist of the story. He is ten years old, and he has a lazy eye that refuses to respond to treatment. He is highly intelligent and suffers a lot of harassment from classmates because of it. He feels uncomfortable at home too, because he is the middle child.
By Watson is thirteen and a handful of trouble. He loves to push the limits of his parents patience, enjoys having a tough image, and is dazzled by the gang lifestyle. By enjoys antagonizing Kenny, as well.
