I believe it is because a) CT is a place where you can express yourself without reprocussions...at least negatively. You won't get a hug from your grandma, but won't get cut down either.
I also think it is because several of us are at an age where we lose the security of order. For 18 years, we know what tomorrow brings through the school system. Dead Prez was correct about the equivilancy between school and prison. For the first time in my life, the possibility of failure existed because I was not in school anymore. Faced with these variety of decisions and new problem sets in which we are unable to solve create an anxiety in which is difficult to deal with. And then the old guys like wsw give the advice of "leave the bish or stick it out" like it's all so simple. I am beginning to think he's right more and more. It is so simple...we make it complex, as there is value and meaning in the complexity. I had (and still have) the conception that a simple life isn't worth living. I still struggle with this, and many other answers about the future. I think by the time I get it figured out, I'll be dead...I will tell my grandchildren, but they will be so caught up in the complexity and "This time it's different" they will refuse to listen. I wish I still had grandparents that where alive. I am certian they would have very value advice to give on how to survive this struggle we call life.
