In "Finding Audrey" by Sophie Kinsella, the protagonist reflects on the complexity of understanding the thoughts of a boy named Linus. She acknowledges that his thoughts could range from positive to negative, or perhaps even be completely empty. This uncertainty highlights the unpredictable nature of adolescence and the challenges of grasping another person's inner world.

The quote serves as a reminder to accept the ambiguity of feelings and thoughts during youth. It suggests that trying to decipher someone's mind, especially a teenage boy's, may often lead to frustration, but it's part of growing up and navigating relationships.
