A private conversation

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! ‘
