11th or 12th grade I guess for me. It ended before it got started. He tried to roundhouse me, but I took a step back and his fist went right into the wall. Back then I had a terrible temper, but this time something kept me calm and I just walked away after he punched the wall.
I had this kid in my next class, and by then his hand was all swollen up. The teacher tried to blame me for his broken hand, but one of his friends spoke up and said that I never touched him. I think he was in a cast for 7 or 8 weeks with two broken bones in his hand.
