The narrator responds to Amina's worries about their cultural differences by initially downplaying her concerns. He acknowledges that she is worried about his family's acceptance of their relationship due to their differing backgrounds, but he defends himself by asserting that his family has never had issues with him dating white girls and questions why this should be different with Amina. His tone suggests frustration and a desire to avoid what he perceives as unnecessary conflict.
The narrator's response may not be considered fair. While he dismisses Amina's valid worries about how their cultural differences might be perceived by their families, he fails to validate her feelings and experiences. By generalizing his past experiences and not acknowledging that Amina's concerns may stem from a different context or personal experience, he minimizes the impact of cultural differences, which is an important aspect of their relationship. Instead of engaging in a constructive dialogue, he opts to sidestep the issue, leaving Amina feeling unheard. This could exacerbate the very concerns she raises, indicating a lack of proper communication and understanding between them.
