You know what I hate the most? Someone cancelling on the last minute for anything from a friend for lunch or a date. I dealt with that shit for too long in my last relationship to find out that all those cancellations meant something not good was going on...it is unacceptable. If you are going to cancel, cancel a few hours in advance, not AFTER I got dressed, put on make up, decided on an outfit, and made a special treat. This means you value my time less than your own. If that is the case, why would I want to hang out with you or be your friend?
One female friend was doing this to me all the time (including telling me she got her period - hello you were 27), that I had to end that friendship, that constant cancelling over the stupidest things really wore me out and upset me too much and of course left me with free time that I could have made other plans with - but then screwed because last minute people can't always get together for an impromptu evening.
So it appears I am too nice, and people just expect me to be completely understanding that they can't get their act together and actually go through with the original plans. I don't know if I want to be the nice girl anymore that gets stepped all over and taken advantage of. I need to start sticking up for myself and getting rid of all that negative energy.
