I think most people don't ever mature. It first dawned on me when I was a kid and was watching our local politicians being all ridiculous on TV. They were exactly like stupid cowardly 10 year old boys in front of their school principal. Like they did some mischief and didn't know how to save their asses. "No, sir, it wasn't me, sir, it was Johnny, I have no idea how this country all of a sudden found itself in ruins'. And I thought 'Jeez, they are like the boys in my class. And I actually thought we WOULD grow up.'
I voted 'No', but that was an act of being overly self-critical. I'm now stronger that I ever was before. That stems from a great thing about maturing: I got to realize that the world is not as frightenly kafkaesque as I thought it was. There are rules and regulations and doing the right things will actually keep you on the right track.
