Some of you guys scare me haha.
I'm really a very easy going person. I was voted most laid back person in my class in high school so that gives you an idea of how little I let stuff bother me. Occasionally this leads to me letting things slide when I really, really shouldn't but thats another story.
The only time I ever really raged out I was, I think, 10 or so. It was at recess, at school and this little bastard who had been insulting me non-stop almost every recess every day said something during a soccer game that just made me lose it completely. I literally grabbed him, lifted him off his feet and threw him through the air into a fence. If my friends hadn't been around I woulda beaten this guys senseless and it took alot of people to keep me back till I calmed down a bit. Come to think of it, a couple years later in grade 8 I had a similar experience with the same kid. Only I lifted him off his feet with one hand on the front of his coat and would have smacked him into a brick wall if I hadn't got control of myself. Anyways that really scared the crap out of him so he stopped bugging me after that.
See, when I really lose it, I get freakishly strong due to adrenalin for a short time and it usually scares me at least as much as the other person. It seems more severe in my case, or so people tell me, because I usually hold back from using my full strength because I'm so afraid of hurting someone badly. For example, I once boxed a guy who was easily twice my size if you go by weight (like, 6'3" over 300lbs to my 5'9" 155lbs at the time) for fun at a party. Basically we were at his place and he challenged everyone else to take him on one at a time because he figured none of us could hurt him, least of all me as I'm pretty thin. For the same reason he left himself open a lot. Since I figured I wouldn't be able to hurt him (he was actually a friend as well) I decided to crank him in the ribs as hard as I could a few times. Despite his bulk, and the fact I had boxing gloves on, I left him with very bruised ribs (big purple blotches on both sides).
Considering I'm stronger now that I was then, yeah I try not to rage out.
