When I was in Y7, a girl in my class came in one day with her arm in a cast and sling. I was amongst the many clamouring around to find out what had happened, but she was really off with just me.
Later that day I was called in to see the Head of Year. She had told them that I'd cornered her after school and broken her arm.
I'd done no such bloody thing. I'd gone to another friends house from school, with that friend and stayed there until I walked home at teatime.
I wouldn't know where to begin breaking someone's arm, and given that I stopped growing at 14 and 5'0, I was about 4'6 at the time compared to the girl who was about 5'2. I'm not sure how she thought I'd have the strength to overpower her.
I think the teachers believed me as nothing else came of it, but there was whispering and her friends felt the need to 'protect' her from me for weeks.
I left that school a couple of months later as we moved away, so I never got to the bottom of why she said it was me, or how she actually broke it. I'm 37 now and the injustice still annoys me.
