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

But while he was working, he lost his favorite watch. Before they came to visit, Joe was preparing his home for the kids: cleaning the house and buying their favorite foods.

The watch was a gift from his deceased (已故的) wife when their first child was born, Joe loved the watch very much. He was very upset(沮丧).

When his grandchildren came, they promised him 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 guess when I was cleaning the barn(谷仓）! "

The children looked for more than two hours but could not find it.

One grandson went to search(搜寻) the barn again, and he asked the others not to follow him and to keep silent(安静的).

He was there for about 15 minutes and then rushed to his grandfather. He found the watch!

Joe was surprised and asked how he was able to find it. The little boy said: ;'I sat there without making a noise, and the barn was so silent. After a few minutes, I heard the 'tick, tick' sound and found the watch."

Joe hugged him and thanked the little boy.
