Mine isn't lighthearted really. I posted many years ago when my youngest daughter (aged 7ish) had been playing with a group of children in our street and an older boy she knew from school (he was year 6 so 10/11) had started hanging around. He was all she talked about for a few weeks, he would play with her at break-time and then at the weekend he would be in our street and playing with her and the rest of the children. It went on for maybe 2 or 3 weeks and there was a mixed age range of children playing out so it was nothing unusual, other than I didn't know where he came from.
I didn't think much of it until one day she came to me sobbing, he had trapped in our shed and although hadn't touched her had been saying she was his girlfriend and they needed to kiss and she couldn't see her friends, she was only to play with him, he was very forceful from what I could work out between DD's sobs. Luckily one of the other children heard her scream and opened the shed, the boy ran away.
I didn't know what to do because I didn't know where he lived, DD didn't know his surname or anything. So I asked on here if I was right to speak to the Head Teacher about it, to make sure he wasn't allowed near her at break-time and to explain to him how terrible it was for him to make her so scared and to try and force her to be his girlfriend. My thread title was something like "Boy behaving inappropriately with my daughter".
The responses I received where by and large appalling. I had name-changed and people I had made friends with on Mumsnet and moved over to Facebook with, were taking the piss. I had overreacted, typical that I think the boy was going to hurt her - it was laughable that my adult mind went somewhere dark, the poor boy was just lonely and wanted a friend. How dare I put this on the Headteacher, this happened outside of school time it is nothing to do with school.
It was truly horrible and I decided to ignore the advice and contacted the Head the next school day. She was disgusted, told me I had absolutely done the right thing coming to her and that "there will be consequences and I will make sure the boy is supervised during break time and kept away from DD".
I came back to the thread under my usual, known, username. I wanted to let those that had been awful to me know exactly how wrong they were. Funny enough not many of them came back to apologise.
It's maybe 10 years ago and every now and then it randomly pops back into my head.
