My daughter is 13 in 2 weeks. She has a girl she is not friends with in her year, let's call her C. We have a very small high street which the girls sometimes go to on a Saturday or for an hour after school. On a few occasions now my daughter has told me that when she is with her usual crowd of about 5 girls they have bumped into C in the high street and she had been bragging about shoplifting in SuperDrug. The next few times they bumped into her she then got things for the group but my daughter three times said she didn't want/need anything. She told me about this each time and I told her she had done the right thing. On the fourth time the girl got everyone a nailvarnish and my daughter said she felt pressurised into getting one as everyone else did and because she had kept saying no before. She told me this last night. So I explained to her how bad it was and told her if she ever bumped into her again to just say she didn't need anything. I'm not sure what else to do though. For example, I am friendly with the other mums in the group, one is particularly close. Do I tell her that her daughter has regularly received 'stolen goods'? I don't want to tell the school as it will be obvious that 'one of the group' has told the school and this girl is also a vile bully so I worry of the consequences, I know of several horrible things this girl has done to other girls, outside school in particular as she gets the school bus home (my daughter doesn't) and this is technically out of school. I did also say if you see her in town again before she even asks think of a lame excuse that you need to go home (tummy ache, etc) and then walk away and ring me and I will come and get her.
I have no idea what to do really, any ideas??
