I had alot of trouble in school back in the day, too. When i was 4 I was kicked out of preschool because I couldn't interact with the other kids at all: i wouldn't share, i couldn't play with them--- i was a little terror. That's how the whole thing started about getting me to Catholic school with the nuns. I was always picked on through school. Some of the teachers thought i acted the way i did on purpose to anger them.
In 9th grade some kid kept pestering me in science class so i jabbed him in the hand with my pencil. It didn't pierce him or anything and the teacher had seen him being a butthead so the teacher didn't send me out or anything. He never pestered me again, though.
I received alot of "butt-whoopin's" when i was a kid--- this at least taught me to try harder not to act up, and i definitely learned that some things were definitely not O.K. to do by any means. When i was about 4, my i wanted to eat a can of peas, but she said no. So i waited for her to lay down. Then i clocked her on the head with the can of peas. Never did THAT again. I learned to do certain things and act certain ways the way other people said I should, but it always seemed harder to do. I did ok in school, though, gradewise.
