I went to the top of a high-rise hotel, entered the spacious bar, and ordered a Heineken. It took ten minutes for the beer to come. Meanwhile, I planted an elbow on the armrest of my chair, rested my head on my hand, and shut my eyes. Nothing came to mind. With my eyes closed, I could hear hundreds of elves sweeping out my head with their tiny brooms. They kept sweeping and sweeping. It never occurred to any of them to use a dustpan.
