OK I'm asked out by a friend of mutual friends. We've met a few times, he's funny, kind and attractive - I like him - we arrange Friday - my first real date in 5/6 years. Friend says her ds has a sleepover with a friend (also of my ds) on Friday and asks if I can bbsit her ds on Saturday so she and her dp can go out - that's fine I have him almost every other week/weekend (inc new year's eve when I stayed in to bbsit this would be third time this year)
Then lovely man says can we make it Sat as he had forgotten he'd promised his kids to take them to see a film only showing Fri.
So I say to friend I will stay in if necessary but could she ask mum of boy who has asked her ds on Fri to make it Sat. This mum is a really nice positive sweet person who wouldn't mind at all being asked and will change if she can and no hard feelings if not.
Friend is a bit upset with me and says fine she'll cancel her plans as cant ask even though I have said I'll stay in if other mum says she can't change days.
Would I be unreasonable to say "oo well thanks if you are sure" and happily skip off on my date?
