ds1, who is 13 this year, goes to the same school as a girl along the street. She has a younger brother who is roughly the same age as my ds2 who is 7 this year.
Lately, this girl and her brother have been calling on us and playing with ds1 and ds2. They play outside and also come into the house to go on the Wii and the computer. They behave well and there's no issues.
However, today ds1 told me some things about this girl and how she got one of his friends into trouble at school. She told the Head of Year that this boy had told her he wanted to have sex with her and asked her if she would do it. The boy was very upset and denied it. Apparently, this girl has a bit of an eye for the boys and isn't above saying things that aren't true. Some of the girls at the school have been putting it around that two of the DT teachers are paedos 
ds1 says that he doesn't want to play with this girl anymore and I'm feeling a bit worried. I don't want someone like that coming into the house because she could return home and cook any sort of tale up if that's what she's like 
Would it be reasonable to stop her and her brother from playing with my two because I don't want any trouble? I just want a quiet life and we had problems with a 'bunny boiler' at primary school who went around telling tales on the boys and setting her dad on some of them.
The girls seem worse than the boys these days
ds1 is just starting puberty and I can't be bothered with these kinds of silly dramas.
Should I steer well clear?
