I cannot handle odd numbers either. My television and stereo volume HAS to be on an even number at all times.
I check the iron, curling iron, etc... constantly. Sometimes I am half way down my street and have to turn the car around and double-check. My husband now knows to check those things before we leave.
I am obsessed with matching. My clothes, household items, etc... They HAVE to match or it drives me crazy.
If I lose something I will tear my house apart until I find it. I become completely obsessed with finding that item, it is ALL I can think about.
This list could go on all night...
