根据短文内容回答下列问题 Bobby came from a poor family. He wanted to buy his mother a Christmas present, but he only had a dime(十分硬币). He walked from shop to shop and finally came to a flower shop. Bobby asked if he could buy just one flower for his mother as a Christmas present with a dime. The shop owner said, "You just wait here and I'll see what I can do for you."
The shop owner came out a little later with twelve beautiful roses, "That will be ten cents, young man. I just happen to have some roses on sale for ten cents a dozen(一打). Would you like them?"
Bobby took the long box from the man's hands and left the shop happily. As the shop owner returned inside, his wife asked, "Who were you talking to and where are the roses you took out?"
The man replied, "This morning while I was preparing to open the shop, I thought I heard a voice. It told me to put aside a dozen of my best roses for a special present and I did so. Then, just a few minutes ago, a little boy came into the shop and wanted to buy a flower for his mother with a dime. When I saw him, I remembered my experience many years ago. That time I was a poor boy with nothing to buy a Christmas present for my mother. A man that I didn't know stopped me on the street and told me that he wanted to give me ten dollars. When I saw that little boy tonight, I knew whose voice that was, and I put together a dozen of my best roses."
