Lol. Not at all. I remember when I thought 30 years old was really old, now, I don't even see it as middle-age. Lol. In some ways, I feel like I'm some ancient hag or something, but, then, I'm 20, still (hopefully) have several more decades of clear mentality. I still consider some people as kids even when they're 25.
PythonWallace, I've done some incredibly stupid things that I thought were cool as a young teen, not half as innocent as snatching leaves from trees, but, what I meant by that was that teens do that ALL the time. Watch a highschool once, besides seeing young girls dressed in less clothing than a stripper, you'll also see kids goofing off and jumping around like a bunch of monkeys, it's normal.
