Why did the writer complain to the people behind him?
Last week I went to the theatre. I had a very good seat. The play was very interesting. I did not 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 actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. 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!"
