During the week, my dad asked me if I'd bring my DC to see him and my mum this weekend and I said I would.
Then yesterday, DS2 had to be picked up from school early and school couldn't get hold of me or DH so rang my parents, who went to fetch him and dropped him to me.
DS1 was also off school, so both DC were in the house and both my parents were in the house. I asked them if they'd like a coffee and my mum said no because they had to go right now because they were going out, and they left.
About half an hour later, me and DS2 went to my parents house (I work there) and I expressed surprise that they were in. My dad asked why I was surprised and I said that mum had said they were going out. Dad said they were but not for a few more hours.
Roll on to this morning, I've just text dad to ask if he still wants me to take the DC round, and he does.
AiBU to be a bit annoyed that they could have spent time with the DC yesterday but choose not to and now I have to spend part of my weekend taking the DC to see them?
It's not really the time itself that's annoying me, more the principle I think.
