I've ummed and aghhed over whether to post this but decided that if anyone can help/reassure, it's you clever people! Our neighbours have been living here about 8 months. She has been married before and has children, who it seems she left with dad in order to move in with new man, with whom she now has a baby. At about 9.30 on Saturday evening a little girl knocked on our door. She was the woman's daughter who we have seen only to say hello to when she's been visiting her mum. She doesn't know us at all. She was very upset that mum's new man and her brother (who is a young teenager; the little girl is 8) were arguing so she had left the house and was refusing to go back. her mum was at the pub. Neither the man nor the girl's brother came to fetch her or to see if she was ok. I calmed her down. Mum arrived after about15/20 minutes apologising byt girl refused to go back to the house with her; she kept saying she wouldn't stay there anymore. In the end, we kept her till a taxi arrived and she and her brother went back to dad's. Neighbour has said nothing to us about this, not even thankyou. This is the second time something weird has happened; last time it was the woman who arrived at our door upset. We hear arguing a lot of the time, mostly her shouting at him. My mum thinks we should ring social services and I must say, I feel this too - dp thinks we should see what happens next. The fact that the girl and her brother don't live there makes it less clear cut I think. What do you all think? I haven't changed my name for this because I think if this woman happens to read mumsnet she maybe will see that this behaviour is very odd and think about it.
