Snap bumblequeen. I wasn't too unlucky. The worst I ever had was boys shoving snow down my top when I was about 15. And at the time I didn't even see it as a sexual assault, which it was, and in broad daylight on the hockey pitch, what upset me was that there was gravel in the snow and they scratched me and it was just horribly humiliating. One of them said "well we can't do this to ((*&^^%$" (the name of a really popular girl who was sort of revered, I can't explain i better than that). But they felt free to grab another passing girl and I think there were about six of them.
Also, another time, a boy whose locker was beside mine gave me a dead leg. I was limping.
When I started my second mixed school one boy spread it round that he knew me from our home town and that he'd shagged me on the beach (wtf?) but that was taken to be true. I was 16. I only found out that the whole year knew very little about me besides that after I left.
To be honest, the girls were never as vile to me as the boys were. I am not hideous, I am now sporty and normal looking, I have 'scrubbed up' as the decades rolled by, but in school I was very ordinary I think and if there's nothing that boys will mock more than a girl that is sexually unappealing. It's like you have NO right to exist almost.
Couple that with being in a predominantly boys school where the teachers still hark back to the good old days of all boys, and fuck me, but it's a jungle for girls! I was like catniss trying to survive my school days!
