As for bullying, it should not be tolerated in schools or on the schoolbus, or anywhere really. I feel like schools need to come down hard on kids who fight and especially kids who edge them on. That can be hard to do, but bullying i think is a result of attitudes people have that is not necessarily a part of our nature, and we need to discourage those attitudes (the "I'm entitled to x, y, and z" attitudes). It is a myth that bullies have low-self esteem, and self-esteem programs are misguided. Bullies generally think too highly of themselves and need to be taken down a notch.
