Do not Go and Kick Ass

The class bully, who was talking to his mates, walks toward me. He grabs my right hand. Like, what's his problem? He shoves me, but not too hard, I only stagger but I don't fall, then he smiles and nods mockingly. His mates and buddies laugh at me. Some students in the corridor snigger. Others are polite enough not to laugh or watch, but they don't help because they admire the bully or because they know him more than I do, and usually he only bullies the new students, like me. Maybe they think I need a beating or a lesson, being the new student and all, so that I don't appear stuck up or something.
