In the poem "Incident," the family takes several actions inside the house. Firstly, they welcome the narrator, who is a young African American boy, into their home. They offer him a seat at the dining table and share a meal with him. The family also engages in conversation with the narrator, asking him about his experiences and offering their sympathy.
Based on the actions of the family, we can infer that the experience had a profound effect on them. By inviting the narrator into their home and treating him with kindness and respect, the family demonstrates their empathy and understanding. Their actions suggest that they are aware of the racial prejudice and discrimination that the narrator has faced, and they are trying to create a safe and welcoming environment for him. This indicates that the experience may have made the family more compassionate to the struggles faced by African Americans.
