     Once in a village, the villagers built a new church building and people came from far and wide to see it.

They admired its beauty! They said it was the most beautiful building in the world. Up on the roof, a little nail

heard the people praising everything about the lovely structure - except the nail! No one even knew he was

there, and he became very angry and sad.

     "If I am not important, nobody will miss me if I quit!" So the nail then released (松开) its hold, got down

from the roof, and fell into the mud.

      That night it rained and rained. Soon, the board that had no nail was blown away, and the roof began to

leak  (漏水). The water flowed down along the walls and over the beautiful pictures on the walls. The plaster (石膏) began to fall, the floor was ruined, and the Bible was also ruined by water. All this was because a little

 nail decided to quit!

     But what of the nail? While holding the board, it was not known by others but it was useful. Buried in the

mud now, it was useless and would soon be eaten up by rust!

     What the story wants to say is that every member is important to a whole group!

     You may, like the nail, feel not important at times, but just like the nail, your absence is felt. A big building

might fall to pieces. You are important to a group even if you are small.
