I'm in law because I love telling people they're wrong. It's added inches to my e-peen in internet arguements. I can just wave it around and argue from authority.
The feeling of crushing someone's dream in court is just unforgettable.

I helped you parents divorce, DQN. I play part in the misery of the world. I defend the rights of the accused when no one else will. I am the Man, and in this way I can rebel against my hippy parents.
