As a child, I believed that one food touching another on my plate "contaminated" both and I would refuse to eat it. E.g., the meatloaf could not touch the potatoes or the corn, etc. Even with spaghettit and meatballs, the meatballs had to be on a separate plate and not touch the spaghetti. My VERY patient mother obliged me by serving me in separate small dishes, or at least in a compartmentalized plate to keep the risk of "contamination" to a minimum. (And don't even let me get started about how this complicated visits to a restaurant!) Years later, I was very surprised and humored to see that the TV character "Monk" has the same little food fetish! I guess I was a little OCD in my youth and didn't even know it.....
