I turned to the flyleaf and wrote: Two classes: both uncomfortable and dirty. No privacy, no relief. Constant stopping and starting, broken engine, howling passengers. On days like this I wonder why I bother: leaving order and friends for disorder and strangers. I'm homesick and feel punished for my selfishness in leaving. Precisely what Crusoe says on his island. Impossible to get comfortable in this seat. A jail atmosphere: the brown walls and dim light of the condemned cell. Noise, too: a factory din, our pile-driving sound, hammered back at us through open windows from the close walls of jungle beside the track.
