I've been trying to arrange to get my parents (not local) and dh's parents and siblings (all local) together to celebrate dd's first birthday. Not a big thing, just tea and cake whenever people were free. It's been a right nightmare trying to find a time, I don't expect anyone to make it a huge priority so have been trying to fit in as best we can.
We thought we had found a weekend when most were free and were happy with that, but it turns out my mum and dad can't do it because my 28 year old sister wants them to give her a lift to the airport for her holiday.
AIBU to think my sister is a grown up and should sodding well get the train to the airport? She backpacked alone around South America for six months fgs, she's perfectly capable.
