In John Irving's "Last Night in Twisted River," Ketchum reflects on the nature of love within a couple. He suggests that partners often express kind and comforting words to each other, even when circumstances are challenging or they shouldn't feel positive. This sentiment highlights the supportive dynamics that can exist in romantic relationships.

Moreover, Ketchum notes that loving couples tend to create their own unique set of rules that govern their relationship. These personal guidelines, although subjective and perhaps unrealistic compared to external societal norms, hold significant meaning for the couple. This underscores the idea that love can shape perception and reality, allowing couples to navigate life in their own way.
