When I was fresh out of secondary school, I found a job cleaning the elegant home of an elderly couple. Among other duties, I had to dust their many important carvings and collectibles as well as pick up after their pets.
One day I found two ivory fossils on the floor beside the bookcase, so I put them back on the shelf. The next week, the same thing happened. That afternoon my employer came into the room, her faithful dog behind her. Looking around, she eyed the bookcase. “Lily,” she asked the dog, “how do your bones keep getting up there?”
