I saw an old lady's face once on a Japanese train
Half-lit, rich with soft luminosity
She was dozing, straight upright,
Head bobbing almost imperceptibly

The wheels were playing fast in 9/8 time
Her husband's friendly face suddenly folded up in a sneeze...
Across the straight a volcano blew a white-smoke flag of surrender

-Bruce Cockburn ("How I Spent my Fall Vacation", Humans, 1980)
