In this short scene, Mr. Lee tries to cheer up his friend, who has just lost his student identification card. He tells Lee that he can give him the card back, but he has one condition: "hang out just night" . In other words, he says, instead of studying, he'd rather hang out with his friends. He also says that anyone who scores 80 on a 150-point exam must have a "learning disability" , meaning that they're unable to read or write. Lee says that he's just applied for a new card, so he doesn't have to worry about giving it back to him.
