The narrator reflects on a conversation with his wife before they meet an old acquaintance. She states that the woman is facing a marriage crisis, but the narrator sees this as a simplistic and insincere explanation. In his view, at the woman's age, such crises are arguably unlikely, leading to a feeling of resignation rather than turmoil.
This insight suggests that the woman has likely reached a stage in life where tolerance and adaptation take precedence over romantic struggles. The narrator's perspective implies a deeper understanding of relationships, where older individuals may prioritize stability and acceptance over conflict.
