Good Night, Atrium
The Fenestration Committee is not known for children's books. They are known for publications on window theory, proportion, and the ethics of glazing. They produced this book at the request of a Committee member's grandchild, who wanted a story in which the building said good night.
The building says good night to everything: the load-bearing walls (which accept the good night with characteristic stoicism), the windows (which let it through), the floor (which has been there the whole time and would appreciate the acknowledgment), the ceiling (which is not looking), and finally the atrium, which the book describes as 'the part of the building that holds the air.'
The atrium says good night last. It does not say what it is saying good night to. The reader decides.
Harold bought twelve copies of this book when it was published. He has given away nine. He still has three. He will not say which three are left or why those three specifically.
