The knocking was always at odd hours. I would be occupied, lost in thought, and the knocking would startle me out of my reverie and demand attention. At the door, nothing. This happened on and off over the course of a few days, and was beginning to become rather annoying.
This time I was lying in wait when the knocking came. I snatched the door open to find a large bird poised to knock again.
“Never” I said.
“More?” It asked.
