A Parable

Seen in this post (which is interesting in itself, since it gives a good capsule summary of the "Generations" thesis of sociologists Strauss and Howe):

There was a merchant in Baghdad who went to the market with his servant. There they saw Death, who stared at the servant in what seemed a threatening way. Later the servant said "Master, lend me a horse. I shall ride to Samara, and there Death will not find me." The merchant did so, then returned to the market, where he again saw Death, whom he approached and asked why he had stared at his servant in such a threatening way. Death responded, "I wasn't threatening him. I was just very surprised to see him here in Baghdad, since I have an appointment with him in Samara later this afternoon."
