when people cancel plans but don't bother letting you know they've been cancelled. All the time I'll make plans with this one friend and she'll be fine with it. Then I won't hear from her for a week. Then the night before I'll ask her what time she wants to meet and she'll go "oh yeah, I can't come, sorry".
couldn't have mentioned that last Monday when I first asked you what time you were free? Or even just whenever you realised you couldn't make it?
I have a similar friend. It's really annoying. Whenever we plan to meet I can't reach her the day before or actual day to make sure it's going to happen and then last minute she cancels. So why did you even bother to ask then? I even started to plan the time we've set up for myself because chances are more likely for that to happen.
