I've only cried like 7 times during the entire course of my life, the most embarrassing one was when I was 15 and everyone was making too much noise in the classroom, I kinda broke down right then and started yelling at everyone to shut up while crying and then I just started punching the first person that got close to me and I also started laughing, which is something else that I rarely ever do, so basically I went completely bonkers, I dropped out of High School not long after that.
Still pretty embarrassing to do that in front of so many people, they stopped bothering me after that but I could see in their eyes that they thought I was going to kill them or something, which I really couldn't stand.
