Most bullies in the end get over confident pick on the wrong person at some point in their lives.If it is the case,that the guy had some kind of learning disablity or mental issue, it is not only more nasty to pick on a vunerable person, but it is a bit like taunting a lion or other wild animal. She is lucky she got off so light, and he calmed down, after dealing out some righteous justice, he could have torn her and several others apart and probably got off light in court if he did have these problems. People with issues and size is a very dangerous combination especially in a confined space.
This bytch obviously missed out on bullying 101 know your victim.... I wonder what she has done to other people she deems lower in the food chain than her?
