You are in a spacious waiting room. Outside the window all you can see is thick white mist, from the lighting it seems to be the afternoon. Next to the only door mounted on the wall is a microphone with two buttons, red and green. If you push the red button, anyone inside the closet disappears. If you push the green button when the closet door is closed, whoever’s name you call appears in the closet, having been instantly transported there from whatever they were doing.
