I am supposed to be going out for a meal with friends in a month. I said from the beginning that I couldn't do Friday because it's my parents' wedding anniversary. Yesterday Friend A said she can't do Saturday. Friend B immediately suggested Sunday as we are all free, but Friend A said they should do Friday, just the two of them, and then do another meal in few months which we can all go to.
Friend A and I live quite close to each other, but Friend B lives over an hour away and looks after her elderly mother, so it's unlikely that she'll be able to get out for another meal any time soon. She's only able to come over to visit us because her mother is going into respite for the weekend.
AIBU to think that Friend A is being really selfish about this?
