Friend came down this weekend but staying with family. I had work to do but said I would see her as much as I could. We went for drinks yest and had plans to go for brunch today. Both v easygoing but live far away so can’t see each other as much as we would like. Anyway she messaged at half ten to plan where to meet. I saw the message about an hour later and immediately replied/called and texted regularly to plan. Heard nothing until 3, when she said she had got distracted playing with nephew but let’s still meet. Then chit chat until 4, I say I’m out in town and can she let me know whether we are meeting as I have to do work still. Obviously keen to see her. Then hear back at 6 - she says that my messages have only just come through and that they are now at the station but she loves/misses me. Had figured by this pint we wouldn’t be meeting so called family for a chat and gone food shopping. Would aibu to say to her, I get that you were busy and we hadn’t made concrete plans but next time can you let me know earlier whether you can fit me in so I can plan my day around the work I have to do? Quite annoyed as I have important exams coming up and lost a whole day due to faffing
