A couple of years ago, I went to a lady's house to buy some vitamins. Upon entering the house, I   16  that there was an electronic keyboard on a stand, leaning   17  the wall. Being a piano music lover and   18  , I asked if the woman played. She nodded and added that she had been   19  lessons--at age 54! I told her that it was very   20  that she was pursuing (追求) her   21  to play the piano.
Then she asked me the same question.
"I have been playing for 8 years now," I answered.

I played the song to the best of my  28 , and with my emotions pouring into it as possible. She loved it.  29 I was about to step out of the door, I heard a weak voice calling out, "Young man!"
I turned around. And there was an old lady   30 one little step at a time with the help of another woman. "I wanted to come out to   31 you for the beautiful song that you played. I have been very sick, and it's very hard for me to  32  my bed, but I really wanted to thank you for the song. It made me feel good..." she said. With that, she turned around and walked   33  back to her room.
I was deeply touched by her  34  and felt a deeper understanding for the song. It served its purpose beautifully, returning to one's   35  for peace and joy.
