If the schools I went to even have reunions, I'm not aware of it at all.
You think kids putting a padlock on your locker is bad? Someone once covered my combination lock with spit and mucus.
Other kids would constantly scream at me that I had AIDS and "Garfield's DEAD", because I was obsessed with Garfield comics at the time.
Another kid spit on me from above as I was walking down the stairs. Then he went down himself, told me what he did, gave the finger and ran off. A few days later my mother and I came home to find the police parked outside, because my older brother, who was still in the same school at the time, had supposedly bruised the kid's ribs after I had told my family at home what had happened. My mother told the police that what they kids at school did to me was much worse, and they didn't press charges.
I was verbally, physically, and sexually attacked and all the teachers would say is "just ignore them". It's kind of hard to ignore people when they're throwing rocks at you, screaming at you everywhere you go, blowing cigarette smoke in your face, and making disgusting threats of sexual assault as they follow you back to school after lunch. Luckily that last one only happened once when I told the principal.
Unfortunately I was too fat and weak to beat anyone into a bloody pulp, even if I wanted to.
