Yu and the driving school coach collect cigarettes in the dark. If they don't have cigarettes, they won't make an appointment for you in two subjects and three subjects.
Yes, I said it would take about 50 days when I signed up. After I signed up, I wouldn't be allowed to practice driving without a cigarette. I also blatantly said that none of the three coaches had two packs of Chinese. I calculated that it takes 26 packs of cigarettes to quit, six packs after the exam, and six packs of Chinese after the third grade. I regret it.
