The mother is a resilient Black American woman whose life has been marked by poverty, struggle, and racial inequality. She speaks with a colloquial, intimate voice, using the extended metaphor of a ruined, splinter-filled staircase to describe the hardships she continually endures. Rather than focusing on rewards, she possesses a fierce, practical determination to keep moving upward, even when the path is completely dark and devoid of comfort. Her survival depends on perpetual motion and an unwavering refusal to stop.

The son is a young Black American man growing up in a marginalized, oppressive society. As the silent listener of the poem, he stands at a point in his life where the upward climb feels difficult and the temptation to sit down or turn back is strong. He represents the next generation facing the same systemic obstacles his mother survived, needing her honest, battle-tested encouragement to maintain his momentum.
