When a person should be spoken with, and you don't speak with them, you lose them. When a person shouldn't be spoken with and you speak to them, you waste your breath. The wise do not lose people, nor do they waste their breath.
ConfuciusThe man who in view of gain thinks of righteousness; who in the view of danger is prepared to give up his life; and who does not forget an old agreement however far back it extends - such a man may be reckoned a complete man.
Confucius
