When I was a teen (the demographic most associated with not being able to adapt or to control its emotions), I was positively stoic. You couldn't make this manly man upset (at least for long. The long process of piercing through my defense mechanisms does pay off with a nuclear powered rage, but you have to be committed).
For example, the Threedee that posted on P.Com and early on, on FP, rarely showed anger, swore, or flamed, etc. I was probably much more mature back then.
The last several years have been weird. Its almost like the college version of me is experiencing all the stuff my high school version never did. I would have said "fuck no, I'm not emo" a few years ago, but now I wonder... If only I'd evolve toward possessing useful knowledge and skills, I'd be happy.
