There's better ways to deal with bullies. I was bullied in school growing up by a guy who was a lot bigger than me. I didn't stand chance in a fight with him. So I got creative.
This guy was so arrogant that he didn't put a lock on his door because he was so sure that nobody would touch his stuff. Well I did. At the end of the year he ended up having to pay for some missing books.
Its all water under the bridge, at least to me.
