Didn't read past page 1, but this thread reminded me of a kid from my school.
He strikes you as a smart guy, but he had something messed up upstairs. I am pretty sure that most of the time he was on the level with best students in class, you could hit him with any subject related question and after a bit of processing he would give you an answer, but for some reason if you sit him down and ask him to write down the answer on a piece of paper, he would just sit there for hours staring at a piece of paper. Like by the time everyone has to pass the papers and leave the class, he would usually finish with putting his name on the top of the blank answer sheet.
One day he was the last one leave the changing room after PE class and when whoever was closing the door asked if there is still anyone there, he failed to respond and ended up being locked for 4 hours. Changing room was close enough to receptionist desk so if he made any noise at all, he would be heard, but he remained silent. When coach opened the changing room for the next class, he said this guy was just standing there in the middle of the room. He couldn't even be bothered to sit down, he was just standing still for 4 hours accepting his fate. I don't know what was going through that head, but I guess it was something like "well, I guess this is my life now".
I had two weird interactions with this legend. First, I remember asking him how come his homework is always on point while he's pretty much constantly in vegetative state at school. He said his box only works in cold temperatures so when he gets home and needs something done, he has to put his head in cold environment prior commencing the task. He said when he's home alone he usually has a bucket next to him with cold water with ice or snow during the winter, but he doesn't do that with his mum around because this freaks her out.
Another one was a bit later the same year. That was the day everyone found out he was doing martial arts and was pretty damn good at it. He was standing in the hall during the break, as usual, in his own world. I was trying to talk to him every once in a while. I think he liked some attention and he was actually a really interesting individual. So yeah, one of those days he was meditating in the middle of the hall when I approached him and tapped him on his shoulder. Worth mentioning I was one of the tallest kids in class and I was probably double his weight, that was when were 16 or so; back then I was doing quite a bit of sports so what happened should not have happened lol. He grabs my arm, twists it behind my back and in a fracture of a second I'm landing on the floor with my face and he's on top of me. He let me go immediately and apologised, and obviously we just laughed it off there. But that was indeed one of the memorable moments from my school years

I still have no idea how that dude managed to finish high school, but from what I heard he ended up going to one of the universities with good reputation and now he's working in a decent accountancy firm. Leg.
