Several years before, Mrs. Green was a famous musician who taught       
         
the music at a college, and many of her students succeeded in their                     
business. Live with her husband at home now, Mrs. Green, in common         
         
as some old people, finds her memory is failing. Sometimes she forgets                
what she has done or will do, that often gets her in trouble. Mr. Green                  
noticed it and persuaded her into see a famous doctor who lives                        
in the capital. He bought two tickets to London and then                              
asked her to put it into her handbag while she was playing                             
piano. When they reached the airport the next morning, the old                         
woman said,“ If only I have brought my piano. I’ve left the tickets on it.”
