One day when some government officials were rebuilding a barn(谷仓), they found a mouse hole in a corner and they used smoke to force the mice inside the hole to come out. A while later they indeed saw mice running out, one after another. Then, everyone thought that all the mice had ran away. But just as they began to clean up, they saw two mice squeezing(挤)out at the mouth of the hole. With some efforts, the mice finally got out. However, it was strange that after they came out of the hole, they did not run away immediately. Instead, one ran after the other near the mouth of the hole. It seemed that one was trying to bite the tail of the other.

Everyone was puzzled, so they stepped nearer to take a look. They realized that one of the mice was blind and could not see anything, and the other was trying to allow the blind mouse to bite on his tail so that he could pull the blind one with him to run away.

After seeing what happened, everyone was silent and lost in thought. During the meal time, the group of people sat down in a circle and started to chat about what happened to the two mice.

One serious American official said: "I think the relationship between those two mice was that of king and guard." The others thought for a while and said: "That was why!"

A smart French said: "I think the relationship between those two mice was that of husband and wife." Again the others thought for a while, and all felt it meaningful.

A Japanese said: "I think the relationship between those two mice was that of mother and son." Once again the others thought for a while, and felt this was more reasonable. So they expressed agreement another time.

At that moment, one Chinese asked: "Why did those two mice have to have a certain relationship?"

Suddenly, the group looked back at the Chinese and didn't say any words. The American official, the French and the Japanese who had spoken earlier all lowered their heads in shyness, and did not dare to answer.

In fact, the true love is not built on friendship, loyalty(忠诚) or blood relationship. Instead, it is based on no relationship.
