I'm currently fascinated by the website i am neurotic, where people submit their neuroses for posting. Some weird, some mundane, some crazy.
A lot of these make my own neurotic habits seem rather dull in comparison. For example, when at the grocery store, I absolutely must walk through the produce section first. I don't like to venture to new grocery stores because I am unsure of where the produce section will be.
If you have any strange habits you'd care to share, comment away!
