Aww, cut the kid some slack, and validate what he is saying... Of course he is seeing high school kids act like immature idiots. Lots of them DO. I wouldn't want to go through high school again... it was the most miserable time of my life.
Jorge - yes, there is a lot of immaturity in high school. That's because it is filled with kids that are trying to grow up, and everyone takes a different path. Unfortunately, not everyone is even successful in the end.
An interesting fact about high school kids is that their brains are still under construction.... they go through a significant increase in grey matter in the early teen years, and then through process called "pruning", during which "clutter" is removed. Their brains aren't really finished developing until sometime in their early 20s. Incomplete brain function leads to impulsive, antisocial behaviors.
Maybe your brain is just more complete than your peers?
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
