a private conversation(私人谈话）
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 angrily. i could not hear tha actors. i turned around. 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."
