I don't know if men have to go to the barber, grocery shopping, to the cleaners, to the manicurist, to the aestitician (sure hope not) or have spend time with the nieces or nephews or hang with their boys, but shit... I do.
So when you tell me you want to see me, spend time, hang out, chill, have sex... whatever and I set aside a time to do so, I mean actually carve out time from you, I'm taking time AWAY from EVERYTHING else I could be doing.
When I make a date, appointment, whatever, I THOUGHT you were important enough to miss one of those other things I had to do. (I'm sorry, sometimes real housewives is very fun to watch). But when you break an appointment it occurs to me that you are actually NOT that important as I previously thought. And then I'm upset with myself for interrupting my regularly scheduled program for your inconsequential ass. Then I'm not just going to be mad alone. I'm going to either give you a piece of my mind or treat you with the coldest demeanor EVER.
This is a reaction that men probably think is unwarranted (and that I should probably work on in my lil emotional growth). But if you want to know WHY I feel how I feel, that's it right there. Please try to keep your appointments.
P.S. This could also be called why people who make appointments make appointments, it's not really gender related, I just find that my girls keep their appointments better than my boys.
