- - Hello, Max.

How has you been these last days?

- - That's good!

Then, you haven't had any amusement, don't you?

I've decided to spent all my time studying.

I want to improve the most my qualifications.

- - Go on, then!

- - Tell me, have you seen David these days?

- - No, I haven't, but he has worked double time the last weeks.

- - So, he has returned home very tired and hasn´t contacted anyone of his friend.

I understand him.

If you see David, tell him to phone me.
