In John Updike's "Rabbit, Run," the quote reflects a profound truth about the relationship between individuals and nature. It suggests that nature nurtures and guides us, much like a mother caring for her child. However, once we reach a point of maturity or strive for independence, nature easily withdraws its support, leaving us to fend for ourselves.

This duality can be seen as both a comforting and harsh reality. While nature offers initial guidance and sustenance, it ultimately expects us to navigate life's challenges alone, highlighting the transient nature of support and the inevitable solitude of adulthood.
