My 12-year-old daughter has a friend whom she considers "best friend." She is a very nice girl, very polite. However, my daughter has found out that she stills from her. Nothing serious, but stuff she adores. A couple of times we let it go, but last time she stole three items from her room that she can't replace. We are good friends with the girl's parents, but we have realized that my daughter can't trust her anymore. We can't trust her anymore. Now, I have a dilemma and ask for your input. We have two options: 1) Tell the girl's mom politely and implicitly expect acceptance of guilt, maybe apology, as it has caused a lot of pain for our daughter, 2) Not tell the girl's mom, not tell the girl, and gradually reduce their interactions/relationship. For example, no sleep overs. My feeling is that while we will get the satisfaction of telling them what the problem is, the first option will lead to animosity, which, I worry will cause additional pain in the future for my daughter. What do you think we should do? I would really appreciate your honest input. Thanks!
