This is a cool thread! Yes, this brought me out of lurking.
I hate raw cucumbers. Cukes are the Sheperd of the Devil. The smell and taste nauseates me. Yet, I eat pickles.
I do not eat certain types of meat with cheese. For example. You will not see Angel11E01 eating a chicken or ham or turkey sandwich with cheese. It's disgusting. I will only mix meat and cheese in a cheeseburger, or some dish containing ground beef or sausage.
I count stuff too. I used to count my steps. Then I count cracks in the sidewalk. Actually, I count anything that's repetitive. When I'm driving, i count road signs.
Not a wierd habit but still. I hate vegetable soup. Oxtail soup all that. Gross.
I have to drink mass quantities of water after I eat ice cream. I understand that it's because ice cream contains a lot of sodium.
Let me think of some more wierd habits.
