I prefer to eat salad on a plate rather than a bowl (because it reminds me of 'Red Lobster'). And when I drink, I like to have cubed ice for Iced Tea and crushed ice for my diet coke. I don't believe this is OCD as much as just preferred tastes. However, Obsessive Compulsive Disorder does run in families. My mother has OCD; though not at all as dramatic as the people on the television program. I think it's safe to say that most of her disorder is about cleanliness. We had the cleanest house in town while I was growing up and when we went camping, we definitely had the cleanest camp trailer!
I know this can be a very serious problem for some people/families. I don't want to make light of it but it would be fun if you could comment and share some Obsessive Compulsive behaviors or "quirks" that may plague you :)
