Bullying was common at my schools, but I don't know if the teachers thought it was healthy (forcing kids to learn to stick up for themselves) of if they just didn't notice. Since I was a girl, I only go verbal bullying (also, I established really early in grade school that if you actually HIT me, you were toast, because I actually liked a good physical fight; it was the teasing that got to me) but my brother got beaten up every day, until his voice changed and he learned he could scare the hell out of people by yelling at them...
