In the book "Love, Rosie" by Cecelia Ahern, the author presents a critique of fairy tales, suggesting that they can portray deceptive and unrealistic expectations for children. The protagonist reflects on how these stories breed fantasies about rescue, often expecting a charming figure to arrive and solve all problems. This unrealistic portrayal can lead individuals to believe in idealized scenarios that don't match real life.

As the character comes to terms with her situation, she realizes that the fantasy of a "posh-speaking" hero is not only impractical but also problematic, as such figures often contribute to the chaos in her life. This moment of realization emphasizes the importance of understanding the complexities of relationships and the dangers of relying on fairy tale narratives for real-life guidance.
