There's a mum at DCs nursery (my DC plays with her DC all the time) who completely blanks me in the mornings. She knows who we are as dcs point out and say that's squiggler's/other dc's mum. Fully understand that most parents are busy hurrying off to work in the morning. This morning dc and I were walking up to nursery and walked past her (empty street, only us around) so I looked at her and said hi and she totally ignored us. Wouldn't mind so much except for the fact that our DCs play together at nursery.
AIBU to think it's rude?
