If I know where the line is, I can decide to cross it or stay on my side of it. The problem that I see, is the line kept moving around and that's what bothers me about the situation.

You may have some on your feet, but when you start to smell it and realize you're tracking all over the house, it's time to take your shoes off and clean up the mess you made.
