15 year old goes upstairs to her mum and says "Dad is watching something dirty on TV downstairs, really dirty sex" the mum says "what?? what is it?" so the girl replies "don't know but they were doing that really dirty thing where the man goes on top of the woman"
So to cut a long story short, turns out the dad was just watching a movie with a sex type scene in it. The mum says "why did you say it was dirty??" so the 15 year old says "well it is! the man was on top of the woman!"
The mum says "thats normal, its just sex" so the girl replies "thats the dirty part of sex though, the horrible, rude part"
personally, to me she sounds about 5, not 15. Her mum is also worried (and knows I'm posting about it on here as she'd like opinions).
The girl also regularly says stuff like "I'm never having a boyfriend, I hate boys" etc. Again, more like a small child than a 15 year old IMO.
Or am I being unreasonable and expecting her to act more grown up than she should?
