Dd 13 has a new friend and has gone over there this afternoon. They made a vague plan for a sleepover earlier this week which even this afternoon wasn't certain. I haven't met the friend but they live in a village about 5 miles away with a large blended family. DD's had a very difficult few months, withdrawn from a lot of things, and initially I was pleased she had a new friend but tonight's plans are very fuzzy and I don't know the stepmum or dad at all. AIBU to think that the stepmum should be the one to call me and introduce herself given DD could be sleeping under her roof tonight.
