Do you have any strange eating habits?
When I was a child I refused to eat anything the grew out of the ground. So, to combat my picky tastes my mother would hide everything in a sandwich. Even today, when I eat at home, I make a sandwich from mashed potatoes and vegetables. My wife thinks this is strange.
Then I look at my wife eating. She refuses to allow peas to touch any other food on the plate (OCD?).
