kinesthesia (from hours of gaming).
I was scared shitless of high school before I went in, because my neighbor had his gym clothes urinated on almost daily, but I never had any bullying problem ever. I've no real idea why--my best guess is that I tend to have a very severe demeanor, and that the way I move/walk (I think) is very, eh...disciplined, for lack of a better word. Also not prone to letting my anger manifest in violence, either, so that probably contributed some.
'Course it could just be because I'm Asian, too, so I obviously know kung-fu.
Sorry if I don't have much sympathy for bullies; I had my fair share of them. My teachers were pretty good about stomping bullying out if I told someone, but of course that just helped to make me more of a target and make them just avoid alerting me who was doing it.
Signature updated. Went with an oldie-but-goodie instead of more Lights, because the last two songs have both been Lights.
On a related note, I got electrocuted at work today. 3-5 inch bolt of electricity arcing from the backboard of a basketball game to my knee. It was actually kind of awesome (my leg is fine).
Also, what would the bully have done if he had given the kid a concussion, or ruptured a kidney when he was punching him? It goes both ways.
