Imagine you are with me, working in a mailroom, or maybe a loading dock, or maybe a prison. Imagine you are here. In this room, putting items into boxes and labels on the boxes which tell the receiver what items the box contains. Imagine you just explained to them, again, that the reason your department keeps getting angry phone calls is because the items in the boxes are exactly what the labels say they are. Your coworker is sitting on the safety rail, feet swinging above the floor, and they're looking at you, and they say: I don't understand. They told me the box labeled "Books" contained "Clothing." You don't know how to explain it without telling the whole thing. They say: tell the whole thing. You open your mouth and what comes out is not what you expected. You expected an explanation. What comes out is: there was something, once.
