OMG ! Stealing!

[Emmsmom]

OK, I need some honest opinions here. My daughter had a friend spend the night over the weekend. Everything went fine and they got along great. Well the night she went home she called and said that her mom went and bought her a sweatshirt from a popular store here. My daughter says oh cool. She goes to school yesterday and says oh I have the same sweatshirt at home. She honestly thought NOTHING of it. Then later she said that she also had a shirt on the same day that looked likes hers as well. So she gets home and we go through her closet and guess what. Yep.. The sweatshirt and shirt she had on were my daughter's. I was so mad that I could feel my bloodpressure rising. For one I am NOT loaded but that sweatshirt was a treat for Emmie and it was on sale. The usually sale for 60 bucks. I called the her house this morning and left a message to tell her to bring them to school so my daughter can bring them home. Now I am thinking it would be better for me to go over to the house this afternoon before they get home and get her mother to get them. I told my daughter not to say anything to her at school because it will make things harder for her at school today(my daughter that is). I told her that I will take care of it. Her friend has it rough at home but I don't feel that it is my problem. I also don't feel that I should just let it go either. If this girl is stealing now I hate to think of how she will be the older she gets. So any idea on how I should handle it??
