I have 2 soon-to-be ex friends from uni who do this.
Friend #1
Thursday
Her: sends me a link to a new menu item at our local cafe or a link to a new cafe in town Let's meet!
Me: Hi. Ok, when?
Her: Next Tuesday during our lunch break? But I'm not sure, we'll see.
Monday* *
Me: Are we still meeting tomorrow?
No response from her.
Tuesday night
Her: Oh sorry was not feeling up for leaving the house today, let's take a rain check.
Friend #2
Her: Are you free for lunch anytime soon?
Me: Yes, I'm free on Tuesday and Thursday.
Her: Oh I can't do those days. Anytime else?
Me: Next Monday?
Her: I'm not free on Monday either.
Me: When do you want to meet?
Her: Uhh, I'll get back to you.
She never gets back to me! That, or we pick a date and then she cancels on the day itself because she doesn't feel like eating teppanyaki or whatever we were going to eat that day.
They ALWAYS initiate this conversation, and yet never follow through. Neither of us have kids/work shifts/have jobs that require OT so it's not that either. AIBU to just not bother with chronic plan cancellers anymore? Why do they do this?
