It is true of even the best of us that if an observer can catch us boarding a train at a way station; if he will mark our faces, stripped by anxiety of their self-possession; if he will appraise our luggage, our clothing, and look out of the window to see who has driven us to the station; if he will listen to the harsh or tender things we say if we are with our families, or notice the way we put our suitcase onto the rack, check the position of our wallet, our key ring, and wipe the sweat off the back of our necks; if he can judge sensibly the self-importance, diffidence, or sadness with which we settle ourselves, he will be given a broader view of our lives than most of us would intend.

Paul barely made the train that Sunday night. When he pulled himself up the high steps of the coach, he was short-winded. There was still some straw on his shoes from the violence in the chicken house. The drive had not completely cooled his temper, and his face was red. No harm had been done, he thought. ‘No harm,’ he said under his breath as he swung his suitcase onto the rack – a man of forty with signs of mortality in a tremor of his right hand, signs of obsoleteness in his confused frown, a summer farmer with blistered hands, a sunburn, and lame shoulders, so visibly shaken by some recent loss of principle that it would have been noticed by a stranger across the aisle.
