Occasionally you'll knock on a door and someone inside the building will shout 'Go around!' While this certainly makes sense to whoever is doing the shouting, it is almost of no use to the person who knocked on the door. Go around what? To where? People need to start including more details when they shout 'Go around.' Next time it happens to me, I'm just going to spin in a circle where I stand and then knock on the door again.
