Here's why it's significant:
* Sal's journey: Sal, the protagonist, travels across the country with her grandparents, encountering various landscapes and people. This journey mirrors her own personal growth as she learns about life, loss, and the complexities of human relationships. The "high sky" symbolizes this vastness and the many possibilities that lie ahead.
* Phoebe's perspective: Sal's mother, Phoebe, is a dreamer who often looked up at the sky and talked about "seeing things." The "high sky" reflects Phoebe's perspective on life, her ability to see beyond the ordinary and embrace the beauty of the unknown.
* Mystery and wonder: The "high sky" is often associated with the unknown, with dreams and hopes. It represents the things we don't understand, the things that make life fascinating and full of possibilities.
In summary, the "high sky" in *Walk Two Moons* is a symbol of the vastness of life, the potential for growth and change, and the mystery and wonder that surround us. It's not about the literal height of the sky, but about the way we perceive and experience the world around us.
