Anyone else here have a thing about their food not touching?

As long as I can remember I’ve always had this thing about different items on my plate not touching each other. When I was young I had to eat sandwiches all seperated ie: first a slice of bread, then eat the tomato or whatever, etc., and then end with the other slice of bread. (I don’t do that now, BTW!) Also, I eat all of one thing and move onto the next. I was just wondering how unique I am with this.
