Last week I went to the theatre. I had a good seat. The play was interesting. I didn't enjoy it. A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actor. I turned round, looking at the man and the woman angrily. They didn't pay any attention. In the end, I could not bear it any more. I turned round again. "I can't hear a word!" I said angrily.

"It's none of your business." the young man said rudely, "This is a private conversation!"
