Dear Wei Fang,
It's a long time since I heard from you in last time. Now I'd like to tell you a impressive story that
happened on the first day of my teaching career.
A boy, Li Ming, whom father died a year ago, was late for school. He stood outside the classroom
quiet. I smiled at him and let him come. After a while, he began to cry. Seeing this, I walked to him and
asked what has happened. He told me his mother was ill but he had to get some medicine for her. At the
same time he apologized to me for his lateness. Moved by his word, I praised him for his deeds and
decided to sing a song was named "Mother" for the students. From then on I began to realize we should
respect our parents and did our best to help them. Do you think so? I'm looking forward to your early
reply.
