This poem by Ernesto Cardenal uses vivid imagery to convey a sense of nostalgia and the fleeting nature of life. The poet compares his days to empty beer cans and extinguished cigarette butts, suggesting a sense of emptiness and waste. Life is depicted as ephemeral, like figures on a TV screen that vanish, or cars speeding by with laughter and music that quickly fade. The beauty of life, symbolized by car models and radio songs, passes swiftly and becomes outdated. The poem concludes with a poignant reflection on the remnants of the past—empty cans, cigarette butts, faded laughter in photos, and the sawdust used to clean bars—emphasizing the transient and often forgotten nature of human experiences.
