A private conversation

Last week I went 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 anrgy.I counl'd not hear the actors.I turned round.I looked at the man and the moman angrily.They did not pay any attention.In the end,I counl'd 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.”
