Quite honestly, I'd rather just focus on my own household the majority of the time, but I come from a family that likes to do stuff together for birthdays/christmases.
One family member has a birthday coming up, and everyone keeps saying how we need to arrange something "all together". Birthday person isn't bothered, is very easy going.
Trying to sort something and everyone is going "oh I'm busy that day, can we not do X day?"
"I don't fancy that kind of food, can't we go to X type of restaurant?" Etc etc.
So basically everyone wants everyone else to bend over backwards to accommodate their own preferences despite it not being their birthday and I'm bloody sick of it all ( and I have now said "let me know what you decide between you and I'll go along whatever!")
