From The Chuang Tzu

In The World of Men

I want to tell you something else I have learned. In all human relations, if the two parties are living close to each other, they may form a bond through personal trust. But they are far apart, they must use words to communicated the loyalty, and words must be transmitted by someone. To transmit words that are either pleasing to both parties or infuriating to both parties is one of the most difficult things in the world. Where both parties are pleased, there must be some exaggeration of the good points and where bother parties are angered, there must be some exaggeration of the bad points. Anything that smacks of exaggeration is irresponsible. Where there is irresponsibility, no one will trust what is said, and when that happens, the man who is transmitting the words will be in danger. Therefore the aphorism says, "Transmit the established facts; do not transmit words of exaggeration." If you do that, you will probably come out all right.
