Friend text me and asked to go to a theme park with the day next month.
It was during the week, so I said probably not as I might not be able to get it off work and I don't want to use too much holiday anyway as I plan on leaving my job soon and will have to pay whatever holiday I use back.
Anyway she went on and on about doing it so I agreed and booked it off, asked her who else was going and it was two people who I do like but I'm not friends with.
Then last night she said to me "oh I might not be able to go now". Her reason being that we have a mutual friends wedding anniversary party that evening and she might need to help our friend decorate the room.
She already knew the party was on this day.
Aibu to be quite peed off?
