Were you to ask a time-sweeper, they would tell you one surprising thing: time enjoyed is never time wasted. Cleaning up in a large office full of staggering tedium, the time-sweeper will pass straight by the desk of the woman who is reading a holiday catalogue under the desk, poring over photos of tropical beaches. They will pass by the next desk, where a man is enjoyably wondering what his mother-in-law looks like naked, and stop by the desk of the young man who is counting every minute, and loathing the hours.
