    Joe, 75, lived very happily and had a beautiful family. He had four grandchildren, and they all visited him during their holidays.

Before they came to visit, Joe got his home ready for the children: cleaning the house and buying their favorite food. But while he was working, he lost his favorite watch. The watch was a gift from his wife. She died when their first child was born. Joe loved the watch very much. He was sad.

When his grandchildren came, they told Joe that they would find the watch. One granddaughter asked, "Grandpa, do you remember when you saw the watch last before it went missing?" Joe answered, "I think when I was cleaning the barn (谷仓)."

All the children went to the barn to look for the watch, except little Mike. They stayed in the barn for more than two hours but couldn't find it.

After they came back, Mike went to look for the watch in the barn. Joe asked why he was going there. The little boy just asked the other children not to follow him and to keep silent. He was there for about 15 minutes and then ran quickly to his grandfather. He found the watch!

Joe was very surprised and asked how he was able to find it. The little boy answered, "I sat there without making a noise, and the barn was so quiet. After a few minutes, I heard the' tick, tick' sound and found the watch." Joe hugged him and thanked the little boy.
