I was a bully in school.
I came from a broken and abusive household and at that age I just had so much hatred and contempt for other kids. Especially the ones that seemed to have good happy lives.
Of course I didn't understand that all that at the time. All I knew back then was that I had to hurt people.
Well since I've matured and started to understand my own issues I felt terrible about all the kids I bullied. I was able to track down many of them on social media to apologize.
My point is that you shouldn't go assuming this guy is the same as he was in school. I mean he already has a fat wife so his life is worse than yours. You won.
In fact, you think he's acting afraid, but in reality he might be terribly ashamed and that is why he didn't want to make eye contact. People mature bro.
