I forgot to mention something. Sometimes I'll resort to violence if people really annoy / piss me off. One time in year 10/11 in my graphics class, I spent around an hour working on some stuff on a PC and then the guy next to me switched off the power to my PC for no reason whatsoever other than to troll me and I hadn't saved my work either so I lost everything. I got out of my seat, grabbed him from behind and threw him to the ground. I was so annoyed but I didn't take it any further as the teacher came over and asked if I was OK. He was by far one of the coolest teachers I have ever had the pleasure to have. I told him I was fine but he told me to leave the classroom for a short while to cool off. It wasn't a punishment or if it was, it was cleverly disguised as suggestive advice for my well being lol.
One time in college I was in my chemistry class and these two guys sitting in the row behind me kept throwing paper at my back. The teacher left to grab something so nothing was stopping them from harassing me. I was pretty tolerant but after the 5th time or something they had just crossed the god damn line. I got out of my seat walked out of my row and entered the row behind me where they were sitting. There was a girl I walked passed who was like "it wasn't me!" and I was just like "I know" and I approached one of the guys, put him in a one handed headlock, threw him off the seat and dragged him all the way to the exit and by the time I got there I had calmed down enough so I just left him there. As I was walking back he got up and kicked his shoe at me, which scraped my hand. I was tempted to pick the shoe up and throw it back but I quickly realized he would look like such a fool if I just left the shoe there and therefore make him scamper across the room to pick it back up himself.
There are many other examples as I used to get picked on a lot back in those school days.
