I had ds1's best friend (X) here this afternoon while his parents went to a child free family party. Both boys were at the same b'day party this morning so we brought X home with us at 1pm after the party and his mum was supposed to pick him up at 6:30.
I spoke to her this morning and she asked if 6:30 was still okay, I said it was and that my dcs usually went to bed at 7pm.
I've had X in the past for tea a couple of times and she's been late picking him up so I guessed she probably would be this time too, hence the comment about 7pm bed time.
She eventually turned up at 7:20 . Her excuse/reason was that she'd been to collect her ds1 from the friend he'd been with and they'd persuaded her to stay for a glass of wine (apparently these people had their parents there whom X's mum knows and she hasn't seen them for ages so she felt she should ).
Now I feel that she is taking advantage and she should have either said no, because she had to get X, or she should have sent her dh to collect X as he was driving anyway.
Needless to say, I was too much a wimp to say anything to her but I'm quietly fuming at her inconsideration.
AIBU and what should I have done/said when she eventually turned up?
