In the book "The World According to Garp" by John Irving, the author reflects on the nature of life and its unpredictability. Unlike a classic novel where stories follow a structured beginning, middle, and end, real life often unfolds in unexpected ways. People can reach a point of exhaustion, suggesting that life can be taxing and overwhelming, leading to the eventual conclusion of existence.

The essence of life, according to Irving, lies in the memories that linger after a person's journey comes to a close. These memories embody the experiences, emotions, and stories that shape our lives, even after those who lived them have moved on. Thus, while life may not adhere to the neat narrative arcs of literature, the memories we create hold significant value and remain as a testament to our existence.
