First, I should say that I used to be a bastard, a real nasty, horrible, bullying dickhead sort of character. I have changed since then and have become a quiet, secluded, socially awkward creep. But, for the last few weeks when I have opened my mouth it's been to put someone down, say a sarcastic remark or start a rumour. Today I made two offensive jokes that killed the mood. So how do i stop this inner bastard emerging? Or is this all inevitable because I was a bad combination of genes because I was an accident and I can't just be a normal person I have to be a cocky show off prick or an isolated shy creep?
