in Year 7 I was tormented on the coach going to secondary school. I lived mid way between two villages and the coach picked up the children from one village, stopped to pick us up, and then carried on through the village I'd gone to primary in. My old friends were on another bus from that village.
4 boys in my year made my journeys miserable. Starting off with verbal nastiness, then poking, then punching and then started strangling me from the seat behind by twisting my collar.
Finally a girl in my class had enough and dragged me (physically) out of an English lesson and to the headmaster and explained what was going on. The boys were immediately suspended (elfycat, go home on the coach tonight. The boys will not be on it) and their parents called in to pick them up. They did return to school a couple of weeks later, but were told to never, ever speak to me, or touch me again.
A few years later I was in my final year training to be a nurse. I'd finished a run of nights and went home to my parents for my days off. My dad came up and woke me an hour or so earlier than my 'day' sleeping pattern adjustment alarm and asked if I could go down and look after a young man who'd just been in a significant but non-injury causing car accident (DF was a mechanic with a garage/recovery service). He'd been in a fatal accident a year before on the same bend in the road (as a passenger in a car which hit a drunk man wandering in the road at night) and was very shaken.
I think his day got a whole lot worse when I walked in the door. And I got my revenge by being lovely and kind and caring to one of my bullies.
Another of the boys (now in his 20s) spent an evening chatting up my very pretty sister, and when he asked for her number she laughed in his face and said very loudly in the pub that after the way he'd tormented me there wasn't a cat in hells chance.
