     Much as Robby tried, he lacked the sense of tone and basic rhythm (节奏). But he dutifully reviewed

his lessons. Over the months he tried and tried, and often repeating to me "My mom's going to hear me

play some day."

     But he seemed hopeless, with no born ability. A real bad advertisement for my teaching!I was so happy when one day he stopped coming.

     Several weeks later my students are to have a recital (演奏会). To my surprise, Robby came, asking

to play in the recital.

     "But, it is for current pupils, you dropped."

     "My mom was sick. But I have been practicing. I've just got to play!"

     I don't know what led me to agree, maybe ….

     The recital came. I put Robby up last to play before my "curtain closer", by which, I could save the

recital if … 

     The recital went off well. Robby came up on stage, clothes wrinkled and his hair looked like he'd run

an egg-beater through it. "How could his mom …?"

     Robby pulled out the piano bench and began. It was Mozart's work! I was not prepared for what I

heard next. Like in a dream, I was then woken up by the wild applause, everybody was on their feet!

     "I've never heard you play like that Robby! How'd you do it?"

     Through the microphone Robby explained: "Well, Miss Hondorf, remember I told you my mom was

sick? Actually she had cancer and died this morning. She was born deaf, tonight was the first time she ever heard me play. I wanted to make it special."

     My eyes were wet. He was not a student of mine, but a teacher!
