We have my 14 y/o DD's friend (my friend's daughter) over for a sleepover at least once a month. Usually provide snacks, drinks, breakfast obviously & sometimes, like last night, dinner if she hasn't already eaten. Never gets invited over by them. The logistics make it hard to invite DD over but it wouldn't be impossible.
My annoyance is my friend has never said thank you (neither does the daughter!), never sends her with any snacks or drinks and sometimes like today, has said she needs to be back at a certain time as they're having a takeaway to celebrate pay day. I would have thought they could at least invite DD over too. One time she even asked friend to pop home in the evening so she could join in with the family barbecue, then she came back to ours! Aibu to think it's quite thoughtless and think that either my friend or DD's friend could invite her to join them once in a while? I get on well with my friend, see her once every couple of months but wonder if I should say something
