I had a bad slouching problem, no fashion sense, social anxiety, was rail thin, and at the bottom of the social hierarchy.
In late High School I was picked on less, because I hated being there, had black clothes and long black hair, and played Counter Strike to the point where I gave a speech on it in speech class, which collectively made everyone think I was going to go on a shooting. I've moved on from the things that've happened in school, forgive but don't forget.
My father was a 200+ pound bodybuilder who has a history of anger problems and verbal abuse. As a child, I learned the meaning of fear. In High School, I caught him having an affair via email which is around the time I stopped talking to him with anything less than the fewest necessary words. Now, to pass the time in the recession, I use his weights.
