Wasn't entirely sure this should go in AIBU, as I'm pretty sure that I'm NBU (always room for disagreement however....)
DS1 has recently started swimming lessons at a private, members only kind of place, but he's allowed to have lessons there if we pay each time. Me and DS2 sit in the cafe, colour in etc while we wait(1 hour). I see this woman there every time who I only know to say hello to, who has a boy in my DS2's nursery class. Her older boy is also having lessons, and she swims with her younger boy at the same time as they are club members. She's friendly but a bit bossy for want of a better word, e.g. telling me we should also join so my "poor" DS2 can also swim. Whatever, I'm not getting into a discussion about that with her.
But last week she said her younger DS was moaning the whole time they were swimming and saying he wanted to get out and go and play with my DS2 in the cafe. Then she said she would just leave him in the cafe with me during the lessons and swim on her own. I stood there not knowing what to say then we were distracted by the kids before I could say anything.
Now I don't know what to say. I'm not looking after her DS so she can swim. I don't mind doing a friend a favour but I don't really even know this woman. I need to say something assertive next time I see her but I can't think of anything that's not either rude or a lie.
Any ideas?
