my daughter

Well, you definetely need to get a hold of it now before it gets out of control any further. It is normal for kids to test the waters, but you can't allow it, especially when they are disrespectful. You need to make sure that she stops hanging out with this crowd. Did she have friends before this? And what were they like? I would first of all try to find out why she feels a need to be hanging out with them. It could be she is insecure and feeling a need to feel protected. That is why I hate the fact that they have merged sixth grade with the 7th and 8th graders, for that very thing. One year can make a big difference. If she still doesn't seem to want to talk about it, and continues with that attitude, you will have to get stricter. You have to nip it now, before it gets out of hand. It may be that you will have to get really tough with it her, but in the long run, it will save you a lot of heart ache. You brought her into the world and you need to do whatever you can to make sure that she is successful in this life. Hanging out with a bad crowd isn't the way to go. Don't be afraid to get tough.

Yes, simply start treating her like the thug she is trying to be , ground her for acting rude, take away priviliges for being disrespectful, and BE A PARENT, NOT A FRIEND! Its your job at that age to decide who she can 'hang out' with, not hers. Simply tell her that she is not to be with these kids, and enforce it. Drive her to school and pick her up. She is 13 for god's sake, not 18! YOU are still responsible for here every action, so get off your butt and lay down rules and enforce them. If you can't be home, hire a babysitter to watch her, since she obviously isn't capable of making correct decisions. You both need to grow up and realize just who is in charge right now.
