When I was around 15, there was a family next door with a daughter who must have been around 11 or 12 at the time. Often when I was in the garden playing football with my brother she'd sit in her bedroom window and watch us. She spoke to us sometimes when she was in her garden, but she was a pretty weird girl and we didn't really talk back much. Anyway, one night (it may have happened more than once actually, I'm not sure) when she was sat in her window, she pulled her pants down and showed us. Our reaction was "ok, weirdo, don't give her attention". We found out a year or two later that her dad had been raping her for years. It explains why her dad screamed at me so aggressively when I jumped over the fence to get our ball back one night. I feel sick just thinking about it.
