To be honest I never had the patience to check!
Hmm, let's see, I have various sort of minor Obsessive Compulsive tendancies. Nothing really serious, just little things. Like if I see a pencil on the table with the point facing me, I always feel like I need to turn it around, in case someone gets hurts. Even if the pencil's in the middle of the table and there's no way it could hurt anyone. It makes no sense, yet at the time it does. The only way to get around it really is to tell yourself it's just your mind being silly and force yourself to walk away.
