Why didn't you answer my calls yesterday?
- I am sorry. I was very busy yesterday.
- What did you do?
- In the morning I went to university and I had three boring lessons there and a very hard test. Then I wroteseveral emails to my mother and some of my friends and came back home.
- OK, what did you do next?
- All right, then I was ready to do my homework but Mark called and invited me to go to the cinema with him and his friend Peter. So, I went to the movies.
- I see. What film did you watch?
- It was 'Mission impossible four'. I thought it was interesting.
- Yeah, I liked it too. Did you go home right after the movie?
- No, I didn't. We went to a pub then and I drank some cola and ate some chips there, but the guys dranksome beer and ate burgers.
- So, when did you come back?
- I got home at about two o'clock and of course I didn't have time to do my homework. I went to bed straight away. And now I have so much to do. 
- OK, I understand. I'll talk to you later.
- Thanks for understanding. OK, I must get back to work. Talk to you soon. Bye.
- Bye.
