How do you feel about people walking through your campsite?

My wife takes it to the opposite extreme. If a CG has cabins for rent, I am always curious what is inside the cabin (beds, bathroom, kitchen, A/C, electric, etc). Even if no one is around and it is obvious to me the cabin is not rented at the time, my wife freaks when I go up to the cabin to try and see inside. She is so worried about stepping one foot on someone else's turf.
