what can you tell about the boys parents from his conversation with the old man

They forbid him to spend time with the old man.......... therefore they aren't very understanding.

"Hemingway does hint at the boy’s resentment for his father, whose wishes Manolin obeys by abandoning the old man after forty days without catching a fish. This fact helps to establish the boy as a real human being—a person with conflicted loyalties who faces difficult decisions. By the end of the book, however, the boy abandons his duty to his father, swearing that he will sail with the old man regardless of the consequences. He stands, in the novella’s final pages, as a symbol of uncompromised love and fidelity. As the old man’s apprentice, he also represents the life that will follow from death. His dedication to learning from the old man ensures that Santiago will live on."
