The Pearl

From the text:

"This thing is evil," she cried harshly. "This pearl is like a sin! It will destroy us," and her voice rose shrilly. "Throw it away, Kino. Let us break it between stones. Let us bury it and forget the place. Let us throw it back into the sea. It has brought evil. Kino, my husband, it will destroy us." And in the firelight her lips and her eyes were alive with her fear.
But Kino's face was set, and his mind and his will were set. "This is our one chance," he said. "Our son must go to school. He must break out of the pot that holds us in."
"It will destroy us all," Juana cried. "Even our son."
