It was starting to get dark and Bobby turned to walk home when suddenly his eyes caught the setting sun’s rays reflecting off something along the roadside. He reached down and discovered a shiny dime(一角钱). Never before has anyone felt so wealthy as Bobby felt at that moment.

As he held his new found treasure, a warmth spread throughout his entire body and he walked into the first store he saw.

His excitement quickly turned cold when the salesperson told him that he couldn’t buy anything with only a dime.

He saw a flower shop and went inside to wait in line. When the shop owner asked if he could help him, Bobby presented the dime and asked if he could buy one flower for his mother’s Christmas gift. The shop owner looked at Bobby and his ten cents offering. Then he said to him, “You just wait here and I’ll see what I can do for you.”

The sound of the door closed as the last customer left. All alone in the shop, Bobby began to feel cold and afraid. Suddenly the shop owner came out. There, before Bobby’s eyes, lay twelve long stem, red roses, with leaves of green and tiny white flowers all tied together with a big silver bow. Bobby’s heart sank as the owner picked them up and placed them gently into a long white box. “That will be ten cents, young man.” The shop owner said reaching out his hand for the dime.

Sensing the boy’s reluctance(勉强), the shop owner added, “I just happened to have some roses on sale for ten cents a dozen. Would you like them?”

When the man placed the long box into his hands, he knew it was true. Walking out of the door that the owner was holding, Bobby heard the shopkeeper say, “Merry Christmas, son.”
