The narrator tells us that he'll be back in a week or so. He's not sure why he didn't tell us sooner, but he's pretty sure that it's because he locked his son in the house for a long time without letting him out. The narrator then tells us about how his dad fed his son cold food, which made him weak. He also says that he brought his son to restau so that he wouldn't have to worry about his own health. He says that his dad is only showing that he can't care for himself. He asks if teacher wang has been staying at his house recently, and the narrator says he hasn't. He then asks if he can have a private talk with his son while the boy is taking a shower. The teacher says he'd rather not tell his son the truth, but the narrator tells him to shut up and to believe in his son.
