Dear Annie.

You asked me about the relationship between our students         76.          

in China. To tell you the truth, I was not clear about it,                77.         

either. You see, some boys and girls begin to make friend             78.         

with each other at too early age, though they know little                79.         

about love and responsibility. Another thing that bring us             80.         

trouble is parents and teachers often mistake us for the normal           81.         

relationship between which we have in or out of school.               82.         

For example, if a girl student accepts a call from a boy, her              83.         

parents would sometime like to be told who has made it,                84.         

Will you often have such kind of trouble in your life?                    85.         

Yours

Wang Ying
