There are 4 black kids, 3 Hispanic kids, and ~10 Asians in my grade of 400.
I like most of them, but most of the Asian kids are really weird. :/
Also:
Breaking an arm isn't that tough. When they punch at you (with left hand), stop the fist with your left hand (open handed), then grab the wrist with your right, and twist it so the attacker is facing away from you. From there you can kick the back of their knee, getting them to kneel, then you got options:
1. Be a richard and put your foot to the left of their shoulder and pull their arm up as hard as you can (breaking it).
2. Be nice and tell them to never forget with you again after straining their arm a bit.
That generally ends a fight. :P
