     Once a circle missed a wedge (楔子). The circle wanted to be whole, so it went around looking for its

missing piece. But because it was incomplete and therefore could roll only very slowly. It admired the flowers

along the way. It chatted with grasses. It enjoyed the sunshine. It found lots of different pieces, but none of

them fit. So it left them all by the side of the road and kept on searching. Then one day the circle found a piece

that fit perfectly. It was so happy. It put the found piece into itself and began to roll. Now it was a perfect

circle, it could roll very fast, too fast to notice the flowers or to talk to the grasses. When it rolled so quickly,

it realized how different the world seemed. Then it stopped, left the found piece by the side of the road and

rolled slowly away.

     The lesson of the story, I suggested, was that in some strange sense we are more whole when we are

missing something. The man who has everything isn't in some ways a whole man. He will never know what

it feels like to yearn (渴望), to hope, to come true the dream of something better.
