In Lines 70-78 of Frost's The Death of the Hired Man, the conflict is characterized as 'Man vs. Man' because it involves a direct disagreement between two characters: the hired man and Warren. They have contrasting views on the significance of work and the concept of loyalty. This interpersonal conflict highlights the differing values and beliefs that can exist between individuals, particularly in the context of labor and personal relationships. Understanding this conflict is crucial for analyzing the themes of the poem, as it reflects broader societal issues regarding work ethics and human connections.
