1.) When I'm eating popcorn, I have to distribute the kernels evenly in my mouth. If I get three kernels on one side of my mouth, the next three kernels must go on the opposite side.
2.) I must know when I'm taking the last bite of my food. I hate it when I don't know that I've eaten the last M&M, last bite of cookie, pizza, pasta, whatever.
3.) I love cold pizza. Straight from the fridge. It's great!
