Ok, fully expecting to be told IBU but I need to air (if only to stop me doing so with DSis!)
So, I'm single, no DC, have a good career. While I'm not swimming in it, I am comfortable and own my own home. DSis and her fiancé rent, are less well off but aren't exactly on the breadline. (Sharing this as context)
Anyway, DSis is shortly getting married. They wanted to spend a week in a European city they both loved as honeymoon but couldn't afford it so I offered £350 as contribution, which would be my wedding gift. They accepted, I transferred money. I've now found out they've decided to do a week in a self-catered cottage in the UK. It's clear it will cost less than I've given them.
Now, I fully get I gave it as a gift and so I shouldn't stress about how it's spent. And if they'd fronted up with me and offered the difference back I would have refused. But but but... It just feels a bit uncomfortable...
AIBU?
