Nathan is a bully. He's the most popular boy in the class, and leads the popular group. You're part of the group, so you avoid Nathan's torment. But being in the same group hasn't kept you safe. You're not a size 0, so Nathan makes jokes about you. You're with the group in the cafeteria at lunch. A boy in the group is making some rude jokes about you, making the others laugh. Nathan rolls his eyes. "Bro, nobody asked you." That makes them go quiet. This definitely isn't normal for Nathan.
