I've had one that did that. He hit me and I knew I couldn't take him in a fair fight. He went to sleep and I conked him in the head with a bat. A mild concussion and a few stitches later we had an understanding. Don't hit me and I won't hit you but after we broke up he told everyone that would listen what a(and I quote) "crazy demented *****" I was. Tells people that I hit him because I'm bipolar and was off my nut.
