Politeness is a desire to be treated politely, and to be esteemed polite oneself.

The surest way to be deceived is to consider oneself cleverer than others.

The greatest part of intimate confidences proceed from a desire either to be pitied or admired.

Politeness of the mind is to have delicate thoughts

A great many men's gratitude is nothing but a secret desire to hook in more valuable kindnesses hereafter.

A polite enemy is just as difficult to discredit, as a rude friend is to protect.
