   W: Hey, don't you think playing PC games takes up too much of your time?

   W: I know. You can play as much as you like during the holiday, but not now. It's affecting your studies.

   W: You only become alive and alert at those war games. In class, I saw you doze off.
   M: It's not my fault. The textbooks are boring and the lectures are tedious. I dislike those teachers who love to call the roll. But the games are interesting, challenging and can broaden my mind as well.
   W: I didn't say the games are all bad, but you can't play games all the time. Have you ever considered what you will do if you fail the exams?
   M: Well...
   W: I know it's not easy to resist the temptation, but self-discipline is essential to one's success. It's part of one's character. Look at yourself in the mirror. You look pale and haggard. See, you have nothing but half a life.
   M: Really? Oh, heavens!
