No... it's normal. I've had an incident like that.
I'm talking to someone, and all of a sudden, this fucker comes up (he did this shit for three years), and starts throwing chalk at me and insulting my mother. I walk up to him, kick him in the balls, smash his head on the table, and the wall. Throw him down on the floor, get down, and start punching him (enough to make him bleed shitloads from his mouth, head, and nose). And then start choking him, some friends of mine had to pull me away from him, and he started running away, crying like a little *****.
They looked at me as if I was insane. I don't know if it was the beating, or my voice going Batman, and shouting "COME BACK IF YOU WANT MORE! I'LL BE WAITING!" and then laughing like the Joker.
Anything worse, would've killed him, and for some reason, that's what I intended.
