One cold morning in winter, when I was a little boy, a smiling man with an ax on his shoulder stopped me, saying: “My pretty boy, has your father a grindstone（砂轮）”

“Yes, sir,” said I．

“You are a fine little fellow!” said the man． “Will you let me grind（磨） my ax?”

Pleased with the flattery, I answered, “Oh, yes, sir． The grindstone is down in the shop．”

Patting me on my head, he said, “Will you get me some hot water?” I ran and brought the hot water．

“How old are you, and what is your name?” he asked without waiting for a reply, “I’m sure you are one of the finest boys I have ever seen． Will you turn the grindstone a few minutes for me?”

Hearing the flattery again, I went to work with a will． It was a new ax, and I worked hard until I was almost tired to death． The school bell rang, but I could not get away, because the ax was not half ground．

At last, however, it was sharpened． Then the man turned to me and said, “Now, you little rascal(小坏蛋), you’ve played truant(逃课)! Run to school, or you’ll be sorry!”

“Alas!” thought I． “It was hard enough to turn a grindstone this old day, but now to be called a rascal is too much．”

The memory of turning the grindstone that winter morning sank into my mind． I have thought of it since． Now, whenever I hear words of flattery, I say to myself． “That man has an ax to grind．”
