In this age of ours, I find that almost all of my friends are becoming mere voices.

Not too long ago when friends came, they would fill half the drawing room and their voices would penetrate the four walls and disturb all the neighbors. Now they have all become, step by step, into invisible and untouched beings, whose tiny voices can only be heard by one ear through the telephone, no louder than the mosquitoes(蚊子).

Since this has become a necessary part of modern life, I too have learnt to live with this “ear language”. Many friends have become more distant because they are not very good at this way of communication（交流）, others have become closer through ear language, and there are some friends I know by voice only. There is one particular voice friend I got to know through a very curious incident.

One day my telephone rang. When I lifted the receiver- a young lady’s voice informed me that she was phoning in answer to an advertisement for a night club program hostess. Obviously she had got the wrong number. The incident should have ended there and then. Actually, it was a sweet voice, only her poor imitation（模仿）of Hong Kong pronunciation and intonation got on my nerve and especially the “wa!” gave me the goose flesh. I told her that if I were the boss of the club, I wouldn’t give her a second thought because of her poor pronunciation. The young lady at the other end of the phone immediately came up with a surprising suggestion that, of course in her true local accent, she wanted to learn proper standard spoken Chinese speech from me, because she valued every chance very much. To my great surprise, we became “phone” friends. Every day, at the agreed time, she would ring me up and our “lesson” would begin. And she was tested and interviewed by a radio station in the south and got acceptd. She phoned me for the last time to thank me and to say good-bye. We had already formed a very deep “voice” friendship and have left deep unchangeable vocal(听觉的) impressions in each other’s mind. Any sudden appearance of visual images(视觉印象), good or bad, could only be destructive.
