A control freak.

I've got neatly separated social groups. It's how I like things: compartmentalized. It's pretty rare that I've let things get mixed, because you never know what will happen. I was considering inviting Jess to the Solstice tradition event next Saturday, but then I got this nagging feeling of, 'This may yield unpredictable results' and decided to just close the invite window.

When predictability influences your choices, doesn't that make you a control freak? The term 'Risk Averse' comes to mind, but it's not quite right. There are no Risk Premiums for these kinds of things.
