My sister and I don't see eye to eye on a lot of things so wanted opinions on this. We've just moved house and my niece (sister's daughter) has been talking about sleepover at ours with our two young DC. DH & I have been invited out and I asked sister if niece wants to babysit our DC (basically watch a film until we get back) and sleep over that night. Sister said yes but asked how much she will be paid! As she is family I was never intending on paying her as I certainly wouldn't be charging. I said well I'll be giving her dinner and she'll be sleeping over and can join us next day at christmas fair. Just received message asking if I'll also be paying her bus fair. I think it's about £3 and my sister earns about 5 times more than I do! This isnt about paying money, more about the constant focus on money and tone from sister like she'll be doing me massive favour (lots of other recent things). I thought it would be fun for cousins but the questions about money make me uncomfortable. Aibu? Wwyd?
