Holy Crap

So, I went to a neighbor, and soon to be ex friend’s house for this shrimp taco cook off. The kids came up with the idea at school and we decided to go along with it.
I am Facebook “friends” with her although we don’t hang out often. My daughter approached tonight with some trepidation. She says that my son is more of a friend with this girl than she is.
We had a nice enough time, and then it was time to go home. I told my kids to help clean up downstairs and I assumed they did. The mom told me not to worry about it so when they came upstairs I didn’t go and check that they cleaned up or not.
We left and two minutes after we got home the girl called my daughter to tell her she left a little snap bracelet behind. Then she proceeded to tell my daughter that because she didn’t clean up completely that she was throwing out the bracelet.
WT ever-loving F?
My girl is sobbing. I told her that the other girl was out of line and not a good friend. I am heartbroken for her.
