In the book "House Rules" by Jodi Picoult, the protagonist expresses a recurring frustration when observing zebras. The statement reflects the individual's struggle to determine whether zebras are fundamentally black with white stripes or vice versa. This confusion symbolizes deeper themes of perception and the complexity of understanding; it highlights the human tendency to grapple with ambiguous situations and seek clarity.

This quote captures the essence of how people approach dilemmas and the ambiguity in life. The zebra can serve as a metaphor for various challenges faced in everyday life, where definitive answers may not readily present themselves. Ultimately, it invites readers to reflect on their own experiences with uncertainty and the desire to categorize the world in a clear-cut manner.
