DC’s birthday party clashes with another person’s DC’s party. She got in first with the invite while I was still getting my act together. Can’t change the date sadly. WIBU to still invite the mutual friendship group, even though it clashes? Is it a snakey thing to do? How would I go about it, just add it to the group chat? She feels bad and I’m not sure what sending the invite would achieve really, just feeling disappointed that none of them will be coming!
