Oh, boy, I have stories I can tell.

I am an introvert and went to a snobby school where if you didn't fit in kindergarden, you were screwed. Of course I didn't fit in with the 'right people' and therefore wasn't destined to have much luck. It wasn't all bad, I made great friends to help me through the tough times.
There was one girl in elementary school who was bratty; she thought she was soooo adorable, had many friends, and thought she could act how every she wanted. I'll call her Lucy (like on the Peanuts). In kindergarden Lucy would ask me to hang upside down on the monkeybars when I was wearing a dress b/c she wanted to see my underwear and laugh at me. Maybe she was secretly g
ay 
. Anyway I wised up to Lucy after my mom told me her real motives (I was niave and a people pleaser). Although it was a long time ago, I think I remember hearing her say that if I wanted her to be my 'friend', I should do it.
In 5th grade I had Lucy in my class again. She was trying to get me to go out with the 'geekest' boy in the class. Lucy probably figured we'd make a perfect match. I said I was 'too young' to be 'going out' with people and that 'she should like who she likes and I'll like who I like'. I remember she called me a baby for saying that. One time Lucy told me to "go to help" (which means go to h3ll) one time because I'm sure she thought she'd be a good Cathoic as long as she didn't use the actual word (even though that's what she meant), I told her to "go to h3ll". (I am a Christian now and realized I shouldn't have said that). I don't remember what provoked the incident, but I'm sure it had to do with her doing or saying something against me and me standing up for myself. In 5th grade gym we were playing volleyball and were on the same team. Whenever Lucy missed the ball she just giggled like it was just the cutest thing, but when I missed the ball she yelled and screamed at me. For some sick reason, although Lucy was a horrible human being, I thought she was cool at the time just because she was popular. Bleh.
Anyway, in 6th grade, once again, I had the misfortune of having Lucy sit at my table in 6th grade woodshop. She made fun of the make-up I was wearing (I'd sneak it out of the house) and proceeded to get the 3 other students at the table to get in on the fun and make fun of me as well (don't remember where the teacher was). I remember just trying to smile because I desperatly did not want to cry. In 5th and 6th grades, I remember hearing other students say how mean she was to me and they felt bad for me. Fortuantly Lucy moved not too long after that.
Wow, all that just about one person. Just to make it brief, in my school career besides regular run of the mill teasing, I had little pieces of chewed gum thrown in my long hair as well as other things thrown at me, a 'please kick me' sign placed on my back, a girl who made a huge fuss in the middle of gym class about not being my badmitten partner, and so much more.
Although I certainly don't condone school violence, I can understand why it happens. I feel sorry for those who are so hurt/angry/terrified to go to school everyday that they feel they have to end their own life or kill those who are hurting them as a way out. Although I went to school before it became common, I remember wanting to hurt certain people, espeically when became a teen. For adults who say, "deal with it" or "they are just being kids" - imagine going to work everyday and being in a similar situation. If behavior like that is unacceptable in the work place and violaters are punished, it should be that way in the school.
