I need help about what to do
Hi everyone so first off last Friday I was walking through the crowd at my school after lunch. I'm a nice guy and I only did this because he tried to literally kill me! But I was walking just to my 5th period when a person running by slams into my. Ack pack and sends it to the left. Well I just happens to have the guy that thinks he can beat up everyone behind me and my backpack hits him. He pushes me forward and into another person. I turned around to tell him that it was an accident when he takes a swing all hard at my head! It hit me in the back of the skull and gave me a nasty bruise but I backhanded his nose then punched his penis, but I only did it because he practically gave me a concussion and my head felt strange after that. Well my reall problem is that when I just walked away after I did that ( which now that I think of hitting him back was not the best thing to do) I heard one of the stupid football players laughing at me and I heard him say " he's as weak as **** hunh while the other guy was bent over with a bloody nose, and looking at me like he's just going to shoot me on Monday. And I'm not afraid of him, the reall problem is that the other stupid football player is in my 1st period and I have to walk by his desk to get to mine and he'll make fun of me until the end of the quarter we just started. So I want to know how to get this guy to step off and to stop *****ing me?
