Had last minute plans to go on holiday with a friend for next week. We arranged one night last week and agreed to wake up early the next day and coordinate booking. I missed the early morning window we chose and apologised immediately, said I’d be around all weekend to book. Heard briefly from her and sent several messages over the weekend, eventually saying I was still planning to take that period off but could she let me know either way by Monday am if she wanted to do something - still no reply!! Do I say anything else? She’s not normally flaky but I’m really annoyed by the lack of consideration here.
