Hemingway's short story "A Clean, Well-Lighted Place" explores the meaning of life through three characters - the Old Man, Younger Waiter, and Older Waiter - who frequent a café late at night. The café represents an escape from loneliness and darkness for the Old Man and Older Waiter, who see life as meaningless nothingness. The Younger Waiter has a more hopeful outlook, as he wants to get home to his wife. Through their conversation and the symbolism of the café, Hemingway examines different views of life and ways people find purpose.
