The quote from Jodi Picoult's "Between the Lines" reflects a poignant observation about the transition from childhood to adulthood. As children, individuals often maintain a sense of hope and optimism, believing in the possibility of positive outcomes. However, as they grow older, this perspective shifts, leading to a more cynical outlook where expectations lean towards the negative. This change can stem from experiences that teach them caution and skepticism.

This evolution signifies a loss of innocence, as adults become aware of life's challenges and uncertainties. The author suggests that this shift might also correlate with a lack of recognition for children's perspectives, as society often overlooks their voices. By highlighting this dynamic, Picoult encourages reflection on the value of optimism and the importance of listening to the insights of the younger generation, reminding us of the hope that can exist alongside the realities of life.
