In Victor Hugo's "Les Misérables," the complex relationships between fathers and their children are explored, highlighting the varying degrees of love and attachment. While some fathers may lack affection for their offspring, the bond between grandfathers and their grandsons is portrayed as unwavering and filled with deep affection. This contrast emphasizes the unique and tender nature of the grandfather-grandson relationship.

The quote underlines a universal truth about familial love, suggesting that while parental relationships can be fraught, the love of a grandfather is inherently strong and unconditional. This idea resonates with many readers, reflecting on the generational bonds that often grow stronger over time, showcasing the affection that exists in the later stages of life.
