Someone behind me has just said this about a situation that needs no comment. O’Hare Field in Chicago is not only gigantic, but it is also filled with scurrying swarms of people all day long and most of the night. I finally find a seat near the gate from which my plane will be leaving. My featherweight typewriter is on my lap and I am going to try to write a guidebook for travelers on planet Earth, a short guidebook for people who feel they need direction.
