Here's something I bet you didn't know about me (unless you're married to me and knowing Adam he's probably forgotten).
When I'm playing solitare on the computer I HAVE, HAVE, HAVE to have the aces go red, black, red, black or black, red, black, red. No matter what order they appear in in the "deck" I can't have the two reds together or the two blacks together.
There's no challenging that OCD diagnosis, is there?
(Okay, I'm REALLY going to bed now)
