In Sophie Kinsella's book "Finding Audrey," the importance of maintaining personal boundaries is emphasized. The protagonist learns that it's perfectly acceptable to keep certain aspects of one's life private, recognizing the value of self-protection. This message resonates with readers, encouraging them to feel comfortable in their own skin and assert their needs without feeling guilty.

Moreover, the quote highlights the idea that saying "no" is a valid response. It serves as a reminder that individuals should prioritize their emotional well-being and not feel obliged to disclose everything to others. Kinsella illustrates the journey of understanding and embracing these boundaries as essential for personal growth and mental health.
