My DD plays with a few girls in her class, one she loves in particular and this girl adores her (always runs up to her and cuddles her at school when she arrives, parties etc). The trouble is this girls mum is friendly with two ladies whos DD's are also in the class, so they all go home/socialise together, the girls have sleepovers and my DD is never involved. AIBU to feel my daughter is being excluded on the grounds of the parents being friendly?
