Robert Plant and Allison Krauss: Please Read The Letter
We have a mail chute of sorts. It's a slot in the outside wall of the house that feeds the box which is inside the wall, that is accessed from a flip door that's inside a closet. The box is narrow and not very accommodating for anything larger than a standard business envelope, and as a result, sometimes our mail gets chewed up in removing it from the box (to say nothing about removing our-self from the closet). That said, it's sometimes better for us to have an empty box than a full one.
