W: May I come in?
M: Come in, please. Do you know what time it is?
W: It’s 8:20. I am very sorry to be late again. And I am also sorry to disturb you and others.
M: All right, what’s your excuse this time? (12)Don’t tell me your alarm didn’t go off or your watch stopped. I don’t wanna hear it!
W: Excuse me, sir. I hit the rush hour. You just cannot imagine how terrible the traffic jam is.
M: Why don’t you get up earlier to avoid this time?
W: I’m sorry, sir. (14)I indeed got up early, but my watch is 20 minutes slow.
M: I’m never late for work, you see. (15)I always set my watch 15 minutes fast every day.
W: Oh, that’s a good idea! (15)I’ll set my watch... 30 minutes fast... to avoid hitting rush hour. I promise I won’t be late in future. And I hope you could forgive me once more.
M: That’s right! (13)You are already late for work three times, if this happens again, you will be fired.
