My DD has a lovely friendship group but there is one who stirs up trouble, Sometimes this group of 6 can be 4 or 3 as they do have some different interests but this one girl has to be involved in everything. My DD and another friend signed up for an out of school activity and this other girl just turned up at our house tonight wanting a lift with us to this club. I couldn't say no so i just took her too and my DD has just text to say she is stirring up trouble and I shouldn't have taken her. This is the second time she has done something similar. She just hates not being involved in everything. How can my daughter politely tell her she doesn't want her everywhere she goes??
