Dc at new school. Dd (8)has a new friend. Her home circumstances are difficult and I’m not sure if the circumstances have made the mum weird or if the weirdness of the mum has caused the circumstances. Can’t say what they are without making her very identifiable, but it isn’t drugs or alcohol. Friend came to our house last week (I felt uneasy letting dd go to her house) and now I’m adamant that dd isn’t going there. Return invite has been made. Happy for friend to come to us, but dd won’t be going there until she is a teenager. I don’t know any of the mums well enough to ask, but I’ve picked up some very subtle signs that others think the same.Is there any way I make clear that dd won’t be going there/out with them without being rude...I don’t want 5 years of excuses. Sorry for the vagueness.
