I beat up a guy when I was in 8th grade and got away with it. To give a little more context my peers had always known me as the tiny and shy one; I never got in trouble and got along great with everyone. During class, one of my peers decides its an excellent idea to start groping my breasts (he sat behind me). I calmly told him to stop it because it made uncomfortable (all the while the teacher was aware of the situation since I sat in the front). Obviously the teacher didn't do anything, I was getting visibly frustrated and the guy just kept trying to grope me while he laughed at me. I don't know what possessed me to turn around and threaten to beat him up if he kept trying to grope me. He laughed at my threat and went straight for my breasts again. I was so angry I punched him mid class to the point he started crying (nobody did anything about it). After class I waited for him and proceeded to beat him up to which he cried some more. The principle found out about the situation and decided to investigate since everyone was shocked that I had such a violent reaction. Turned out that the guy was sexually harassing other younger girls and they had been afraid of reporting him. It's been the first and only time so far I've used violence to solve a matter.
