Here's a breakdown:
* Elizabeth: She is fiercely protective of her children and sees the rockpile as a dangerous place. She worries constantly about their safety and wants to keep them away from it.
* Gabriel: He, on the other hand, believes that children need to learn by experiencing the world, even if it means facing some risks. He sees the rockpile as a place of adventure and learning, and doesn't want to restrict their freedom.
This difference in parenting style leads to constant tension between them. Elizabeth's worry manifests in her constant nagging and instructions, while Gabriel's frustration boils over into angry outbursts. Their conflict ultimately culminates in a tragic event, highlighting the devastating consequences of their inability to find common ground.
