     Morison and Philip were classmates. They lived in the same town. After they left school, Morison became

the manager (经理) of a flower shop and Philip became a doctor in a hospital.

     Philip made a girlfriend. He bought a red rose for her each day to show his love, The flowers made her

very happy. Sometimes he took the rose to her himself. But when he was busy in the hospital, he asked

Morison to give the rose to her instead of him.

     One afternoon, Philip came into the flower shop and said to Morison."I'll go to another town to work today.

I have no time to give the letter and the flowers to my girlfriend. Please give her the letter and twenty-four

roses."

     In the evening, when Morison was closing the door of the shop, Philip came."Morison, how many roses

did you give my girlfriend this morning?" asked Philip angrily.

     "I gave her thirty," answered Morison.

     "Why did you do that?" asked Philip.

     "I thought you often bought roses for her in my shop. I want to give her six roses as the gifts (赠品). Six is

a good number, you know," said Morison.

     "How foolish you are!" He threw his letter on the table." Read it!"
