In an email exchange between Stephanie and Rosie, the conversation touches on the insights gained with age. Stephanie points out that growing older brings a certain wisdom, particularly the realization that life is often unpredictable and uncertain. This perspective highlights a common theme in literature where characters reflect on their experiences and the lessons learned throughout their lives.

The quote from Cecelia Ahern's book "Where Rainbows End" succinctly captures this notion of wisdom acquired through aging. It suggests that as people navigate through life's complexities, they come to understand that no one has all the answers, emphasizing the universal journey of seeking knowledge and clarity amidst chaos.
