Final answer:
Robert, the blind man, visits the narrator's home as he was a close friend of the narrator's late wife, which leads to significant personal growth for the narrator.
Step-by-step explanation:
The story in question seems to be Raymond Carver's "Cathedral," in which Robert, a blind man, visits the narrator's home. Robert was a close friend of the narrator's late wife and comes to visit after her passing. The visit serves as a catalyst for the narrator's own personal growth and a challenge to his preconceptions about blindness and connection.
Upon visiting, Robert's character engages in deep conversations with the narrator, which gradually builds into a significant personal experience that culminates in a moment of revelation and insight for the narrator. Robert's presence and actions effectively show that despite physical sightlessness, one can see in different ways, emphasizing the story's themes of understanding, insight, and the various ways in which people 'see' each other.
This transformative visit enhances the narrator's perception of life and challenges his initial discomfort with and prejudices towards people with disabilities, specifically blindness.
