My daughter has 3 or 4 close friends, and one of them is particularly mean to her. I don't know what it is, but she is always calling her names, ignoring her or constantly using her when she has no one else. As soon as someone else comes on the scene, my daughter is immediately dropped and told to go away. This really upsets her as she is not doing anything wrong. I have told her that this girl is being nasty and that she should stick with her other friends who are all very nice.
It must seem a bit harsh, but I would rather that she had nothing to do with this so-called friend who can't seem to stop being horrid. She is 11 years old and hopefully will see sense and realize that she is not a friend but a user. It is her choice and as she gets older she will find out just who her real friends are.
