Don’t give someone the opportunity to flake out on you twice.
If you make plans to meet someone, and they cancel at the last minute because their friend wanted to hang out, or they just realized that American Horror Story was premiering tonight, or because they’re suddenly feeling tired…
This person either doesn’t actually want to see you (so don’t bug them anymore) or they do want to see you, but they have no respect for your time. And if you make plans with them again, they’re likely to pull the same shit. Don’t give them the opportunity.
Sure, things come up. If someone ends up deathly ill the morning of, or gets called in to work, and makes an effort to contact you asap to let you know they’re sorry they can’t make it, that’s one thing. But if someone cancels on you when you’re already on your way to where you are meeting up, they better have a damn good explanation. And they better seem like they genuinely feel bad about suddenly canceling - or it’s fair for you to assume that they don’t respect you or the value of your time.
And you deserve better than that.
