Impulse Control Check

I am a planner. I love my calender. I write everything down, and try to know what's going on before it even happens. I guess that could fall into multitude of categories from being neurotic, to OCD or micromanaging or whatever. But it's me, and everyone who has graced my presence knows this.

So why do people try to annoy me by being "spontaneous" ? ~ which I equate more with being inconsiderate not fun loving. When I ask you what time to expect you for dinner, Im trying to be accomodating to your nature. It's killing me though because I want to say dinner is at X time, be there or be square. When people say they want to play it by ear, that drives me insane. Think nails down a chalkboard. When people ask for something last minute I want to punish them for not having planned better. I'm evil, I know.
