Ugh, I hate that too. It's just so inconsiderate to ask someone to plan their day around you and then disappear at the last minute. Like you had nothing better to do than sit around and wait for her. Then to get all ready to go out only to hear her cancel, very rude and self centered. But, I guess things come up sometimes and perhaps it was an emergency. However, instead of staying in and being pissy, why not ask your boyfriend if he wants to go out to dinner? You're all dressed up with your hair done, why not take a bad situation and turn it into a good one?
