When Jimmy was a boy, he always liked watches and clocks very much. When he was eighteen years old, he went into the army, and after a year, he began to teach himself to mend watches. A lot of his friends brought him broken watches, and he mended them for them.
Then his captain heard about this, and one day he brought him a watch too and said, “My watch has stopped. Can you mend it for me, please?”
Jimmy said, “Yes, sir, I can.” After a few days, he brought the watch back to the captain.
“How much do I owe you?” the officer asked.
“One pound, sir,” Jimmy answered. Then he took a small box out of his pocket and gave it to the captain, saying, “Here are three wheels from your watch. I didn’t find a place for them when I put everything back.”
