This passage further explores the idea that in an apocalyptic environment, care for others can be both a curse and a salvation. Looking after children in particular gives a sense of purpose and meaning to the chaotic, traumatic lives of the adults. On the other hand, the loss of a child—which is, tragically, not an unlikely occurrence in this world—is a nightmare from which many cannot recover. Indeed, the pain and difficulty inherent within caring for other people means that many characters in the novel choose only to look out for themselves and perhaps only one or two select others. At the same time, the sight of people in Hollister helping one another provides a sense of hope for the future.
