In John Steinbeck's novella "The Pearl," Kino and Juana experience a significant disagreement regarding the treatment of the pearl Kino finds. Kino is filled with dreams and ambitions of wealth and a better life, believing the pearl will bring them prosperity and social elevation. He envisions sending their son Coyotito to school, marrying Juana in a church, and escaping their impoverished life.
Juana, on the other hand, perceives the pearl as a source of evil and misfortune. She fears that it will bring harm to their family and believes that it has already begun to attract greed and danger. Juana's instincts tell her to get rid of the pearl, while Kino, blinded by his aspirations and dreams, insists on keeping it and fighting for the opportunities he believes it will bring.
This disagreement highlights the theme of greed versus contentment, as well as the struggles between ambition and the desire for safety and preservation of family. Ultimately, their differing views lead to escalating tensions and significant consequences for their relationship and family life.
