Being inside is cool, but being outside is great. Great until you want to come back indoors. But once you’re inside, what is there to do, but go back outside again? William faces these predicaments about twenty times a day while patrolling. But he doesn’t have to worry, because he has Anna and Ellen to willingly open and close both the back and front doors for him whenever he so pleases. So, being indecisive about choosing to stay inside or go outside isn’t a problem for William, it’s a treat.
