I was physically and emotionally bullied for close to three years of my life because I was overweight. I had a specific bully who would continually punch, kick, and otherwise physically injure me. One day, he shoved me down on the bus ramp and almost broke my nose. It wasn't bleeding, and it didn't even hurt all that bad. You know what I did? I jumped up amidst the laughter and put my FUCKING FIST into is smug face. He got kicked out, and I got no punishment.
I condone this kid. He did what I almost couldn't do. The funny part? I recently saw this guy in a cast. Turns out after I got done with him, some kid that was half his age shoved him down the stairs for bullying him. When he saw me, he came over and apologized. He said he had no idea that this was what I had felt like. We're close friends now!
My point is: An eye for an eye may leave the whole world blind, but its a damn sight harder for two blind men to fight.
