In Richard Brautigan's "Trout Fishing in America," the setting shifts as the day nears its end, creating an atmosphere of tranquility. The evening is approaching, and the temperature is beginning to drop, signifying a transition that feels timeless and eternal. This moment captures the essence of the day's close, illustrating the calmness that envelops the environment.

The imagery of office workers returning home is vivid and playful, comparing them to penguins. This comparison evokes a sense of uniformity and routine in their daily lives, as they navigate the streets of Montgomery. Brautigan uses this metaphor to highlight the mundane aspects of urban life while juxtaposing it with the natural beauty of the evening, inviting reflection on the simplicity yet complexity of everyday experiences.
