The same thing happened to me a lot. It still happens now and then, but I have my revenge not allowing the guilty persons to come to my house for some time, or refusing to talk to them on the phone, or doing the same thing on purpose the next time
In other cases like it often happens *cough* with a precise person from this forum *cough* I get mad... Very.
I don't like waiting for a long time without knowing if the person is coming or not, or worst thing, knowing the person is going to arrive but that he/she's probably taking more time than necessary for some other activity while I'm waiting. That really pisses me off. It's one of the things I can't stand about others
