We always do a big family Christmas with dh's family. There's 17 of us all at dinner and opening presents. We've done it for the last 8 years since I've been with dh.
3 of the 17 are all little kids, ds being one of them.
Every year we buy dh's cousin who's almost 30 a present. And her boyfriend.
She's never bought a present for anyone! We all take turns to open stuff and thank each other and she happily accepts gifts but has never bought so much as a bar of chocolate for anyone back! Even the little ones.
Although it's not about cost it's about thought she has way more disposable income than anyone else in the family. She's earning a lot a shares a flat with her partner who also has a very high earning job. No debts at all and they're saving to buy a house outright.
I've told dh I'm sick of spending time, thought and money on someone who for whatever reason doesn't do it back and that next year I won't be buying for her but he's said it will be embarrassing if we don't get her something and get her two siblings something.
Aibu? Happy to have my arse handed to me if I am.
