- Excuse me, can you tell me the time? There is something wrong with my watch.
- Certainly. It's ten to nine by my watch.
- Your watch is right, isn't it?
- I am not quite sure. It may be two minutes fast.
- I see. Thank you.

- Come and see me tonight.
- I'm afraid I can't. I have a lot of things to do. But if it is urgent, I'll come.
- Oh, no. You may come any time you like.
***
- Excuse me, can I see Mr. Brown?
- Sorry, you can't. He is out for lunch. But he will be back very soon.
- May I wait for him here?
- Certainly. Will you take a seat, please?

- Hallo, Bob! How are you?
- Not so well, I'm afraid. I have a bad cold. It's a pity I won't be able to attend the lecture tomorrow. I have to stay at home.
- You needn't worry. You may have my notes.
- Oh, thank you very much.
