In Cormac McCarthy's novel "The Road," the quote encapsulates a critical theme of the transient nature of existence. It suggests that while 'ever' implies eternity, to the boy in the story, time feels fleeting. This contrast emphasizes the fragile reality of their harsh environment, where hope and permanence seem elusive. The boy’s understanding hints at the complexities of life and memory amidst the backdrop of desolation.

This perspective reflects the emotional weight of their journey, where the future is uncertain. The boy's insight conveys a sense of resilience and awareness that sets him apart from his father, who is burdened by the weight of survival. The idea that 'ever' can feel insignificant highlights the importance of cherishing fleeting moments, especially in a world marred by despair.
