Later, in the hall, she explained that exam day doesn't only mean a day of rest for me - the teachers' only responsibility during the day is to supervise the students while they take exams. Since today's exam a practice test, students don't take it very seriously (indeed, on my way to lunch I noticed about half of the students in each class fast asleep), and teachers aren't concerned about cheating. Because the teachers "can feel comfortable," says Mrs. Yoon, many of them go out drinking heavily the night before.
A hot soup is considered essential to recovery from a hangover, and, luckily for many male teachers, today that is exactly what we had (actually, there's a whole class of soups Koreans consider hangover cures - 해장국, he-jang-guk - one of which is made of blowfish and bean sprouts). The teacher's retort to my "시원하다" comment was a joke, not at my expense, but at that of all the teachers nursing a hangover today. 살 것 같다, Mrs. Yoon explained, is used when you begin to feel better; having taken the first several sips of a steaming soup after a long night of binge drinking, perhaps. It means "I am almost surviving!"
