Each of us is peculiar. Those of us who are willing to admit it have more fun.
Here are a few of my idiosyncrasies:
My closet and drawers are perfectly organized. Everything has its place. Sorting is done by sleeve length, color, style, etc. All hangers must be white plastic and facing the same direction.
Towels must hang straight on the bar, and must be folded evenly.
The paper cutter at the office must be secured. I worry it will spontaneously cut off a finger.
The dishwasher must be loaded a certain way. Joe's cups have their spot, plate location depends on size, etc.
I sleep predominately on my right side because I once heard that was better for your heart (although I've since heard that is a myth...).
If I mess up in my writing at the beginning of a page, I must throw it away and start over.
Symmetry is a necessity!
Like my cat, I thrive on routine.
I'm sure I'll think of more as soon as I post this...
What are some of your idiosyncrasies, you weirdos? ; )
