I have no idea if this is my darkest, but most definately my most violent. I think I've actually said it here, before.
Some kid pushed me into the road, into oncoming traffic, when I was walking home from Middle School one day. Now, I always have either my key or a pen in my right hand, flipping it between my fingers. So, when he pushed me, I stopped my self, spun around, and backfisted the guy... with my key between my fingers. Well, his face was slashed open. Believe it or not, I did not get in trouble. He never reported me to the school or the cops. On the bright-side, I never had to deal with the idiots in my school, or in High School ever again.
