One time in high school I was supposed to go to a movie with a friend of mine, she was supposed to come to my place first and we'd leave from there. She never showed up (and it was the 90s so no texting) so I was just like "okay" and went about my day. Two days later she randomly showed up at my house and asked if I wanted to go. I said no because she was two entire days late and now I'm doing something else, and she got annoyed at me for not dropping everything and going.

I do not understand this.
