I get kind of annoyed when people cancel at the last minute....

A three fourths of me is okay with it, but the other fourth is kind of disappointed.

I mean, I'm okay with people leaving early and such, or if some emergency happened and they need to be somewhere, but I just get kind of annoyed when I'm the one who is going to be driving and someone says, "I might not go tomorrow."
Okay. If you're going say you are, and if you're not, say you're not. I'll be almost completely okay with it unless if we planned it ahead of time (like two or more weeks before the designated date). I get that some other things may occur and some other plans may get in the way or you'd rather hang out with person x instead of me, but if you don't tell me straightforward, I'll be annoyed.
Excuses I am okay with. Vagueness, not so much. Please. If you're going to cancel on me, or anyone else, be straightforward. They'll be disappointed, but understanding. If they're not, then they're weird.

On a side note, I like this song.
