The quote from Larry McMurtry's "Lonesome Dove" reflects a poignant observation about the passage of time and the nature of love. It suggests that as years go by, they can feel fleeting, similar to how weeks seem to slip away unnoticed. This imagery emphasizes how quickly life’s moments can vanish, leaving behind memories of past experiences.

Additionally, the quote also conveys the idea that love can evolve or diminish over time. Relationships may fade or turn bitter, highlighting the challenges and complexities of human connections. McMurtry's words encapsulate the bittersweet reality of life's transience and the changing dynamics of love, reminding us that both time and feelings are impermanent.
