In 7th grade I was still a fat kid and at a football game. Some dude was throwing peanuts at me for the longest time and I could see the looks on everyone's faces around me and finally I just walked up to the dude, heart beating and just wanting him to stop, and punched him point blank in the nose. Dude started crying and I felt so embarrassed and blah blah. Nothing happened because no teachers were around, just the whole of our grade.
From that point on dude didn't fuck with me, even laughed at my jokes. But even well into high school, everytime I saw him laugh with me or whatever, I always thought "He threw peanuts at me in front of everyone and I had to punch him in the nose".
I guess the point of my story is, some people just don't listen to reason. I've been reading a lot of "fat kid went too far", but maybe they lack the ability to empathize.
