I’ve been considering some strange quirks in people I’ve noticed lately. My husband has a weird thing he does when he drinks coffee. I have a couple of nearly obsessive-compulsive disorder quirks – when I’m looking for a greeting card, I tend to rearrange the ones that have gotten out of order. It drives my husband up a wall; he’ll come drag me away from the rack if I haven’t found a card I like within five or ten minutes. And when I eat M&Ms, I eat them by color. In pairs, preferably in “Roy G. Biv” order. My daughter and I were recently discussing the fact that when we are in a traffic jam next to someone towing a boat, we have to fight off the urge to leap out of our car and into the boat, and pretend to drive the boat. While singing the Gilligan’s Island theme song. (Well, that’s me, not her. She’d probably sing a pirate song.)
Where do these strange thoughts and quirks come from? I have no idea. But I know we’re not alone in this oddity. Post your own, if you dare. 
Mine:
I eat my the food on my plate in a clock-wise pattern … starting with the vegestables and ending with the meat.
I check the smoke alarms a lot. And … I mean a lot. I have a fire phobia.
I unplug things too. If they aren’t being used at a particular moment then I don’t see any reason for them to be plugged up.
I know where everything goes in my house and if you move anything … even a hair … I will unconsciously know it and put it back where it belongs.
My husband says that he is surprised I have never been diagnosed with OCD! LOL
