The narrator tells us that he hasn't been back home for the past year, and that he's not sure how his family is doing. He's worried that they must have been lonely. He asks the old man if something is wrong with him. The old man tells him to take it easy. The narrator says that if something happens, he'll feed him to the fish. He then asks if the doctor is a quack. The doctor says that first aid is useless to a patient with a heart attack. The young man says that his medical skills are better than the quack's. He says that the patient needs to be taken care of as soon as possible. The boy then tells the narrator that if he can cure the patient, the doctor has to apologize to him.
