A window has been left open

"This I did not expect at all. It is what I love about life, that things happen which I do not expect. When I was a girl in Blundermeecen, we left the window open for this very reason, even in the winter. We did it because we believed something wonderful might make its way to us through the open window. Did wonderful things find us? Sometimes yes, sometimes no. But tonight it has happened! Something wonderful!" Dr. Meescham clapped her hands. "A window has been left open. A squirrel flies in the window. The heart of an old woman rejoices!” -Kate DiCamillo, Flora and Ulysses: The Illuminated Adventures
