Inexplicably, people in my age group seem to have a propensity for being excessively immature. Examples of things fellow teenagers do that are major pet peeves for me. I think that considering the opportunities we're given, there are far more constructive things to be doing on school time. Well, I just did. It is ridiculous.
Inexperience is no excuse for recklessness.
Strange Adult Behaviors Also, as a teen, I can say that adults can do pretty annoying things. I find this downright hilarious. I know they mean well, but kids find it easier to learn lessons by screwing up all by themselves. The bigger pet peeve though is the one aspect of parent-teen relations when parents think they are always correct. This might not apply to all, but I sometimes get the feeling that my parental units think that they can read my mind.
