It's the morning of the Chemistry Club meeting, and the students are complaining about their failure to pass the exam. The teacher tries to cheer them up by reminding them that they'll be taking extra classes in the summer to prepare for the exam in a week's time. The students complain that the teacher is too loud in the library and that he's not paying enough attention to them. He tells them to be quiet and to rub their hands with a warm cloth so that they won't hurt themselves. He also tells them that next week, the students will have to take extra classes because of the exam's late start.
