My brother and his partner have sprung a surprise trip to Disneyland for my 3 children on me.
We don't have a close relationship although I have tried to invite him to dinner, meet up with them etc. They pop by briefly several times a year on their way to other places and always have an excuse for not having lunch or a coffee. They do always remember to buy the kids expensive birthday presents though.
I am annoyed by them surprising us with such an expensive trip that we couldn't afford ourselves at the moment, especially as they usually don't make an effort to spend time with the children. I haven't said anything to them about the surprise as I am not supposed to know yet. Am I being unreasonable?
