I agree with what a few others have said here and that is Maturity is knowing when to fight and when to back down. I think the reasons parents and teachers try to drill the back down strategy is that when you are young you are usually more willing to fight over any little thing. The more times you fight the more likely it is that you could seriously get hurt, and at a young age you don't have the mental capacity to understand the later consequences for your actions. Also in a young age you can get a sort of mob mentality and all of a sudden 2 kids fighting turns to 4 or 6 and there is just no easy way for a teacher to regain control of that situation.
