Les querelles ne dureraient pas longtemps, si le tort n'était que d'un côté. - François de La Rochefoucauld

In jealousy there is more of self-love than love

It is a great ability to be able to conceal one's ability.

We should make it a rule never to have half confidences. They always embarrass those who give them, and dissatisfy those who receive them. They shed an uncertain light on what we want hidden, increase curiosity, entitling the recipients to know more, giving them leave to consider themselves free to talk of what they have guessed. It is far safer and more honest to tell nothing than to be silent when we have begun to tell.
