The second reason is that they never truly agreed to do anything in the first place. Saying they'll show up somewhere and then not doing so without notification is usually a message saying that they didn't want to meet up with you in the first place. It's a nasty little trick designed to avoid confrontation.
There can be other reasons though.
I remember once in junior high there was to be a party held in school. I had no intention of going, because I can't stand loud music when it's not my kind of music and I don't do dancing, and I don't like parties. A, a girl in my class asked if I was going. I said no. A kept saying "oh come on, it'll be fun." I kept saying no but she wouldn't take my no for an answer so I lied to her face and said I'd go and she smiled and said 'good" and stopped bothering me.
I had no intention of going and I didn't.
The next school day (Monday) she asked me why I hadn't come. I lied and said I had gotten sick, not bothering to try to sound sincere.
Equally phony she said "oh that's too bad".
I'd known A since elementary school and she'd never been nice so I've wondered in retrospect f she was staging a "Carrie".
