What do you do that's weird, that bothers other people?
I have a friend who can't stand watching me eat. Its not that i'm gross or anything, but I eat everything by layers.
If I get pizza, I eat the toppings first with a fork, and then the crust with my hands. When I eat tacos, I eat the inside of the taco, and eat the shell last.
Same goes with cupcakes, and cakes. I eat the frosting and then the cake.
You get the idea.
