All doors open to courtesy.

To speak kindly does not hurt the tongue.

True politeness consists in being easy one's self, and in making every one about one as easy as one can.

The measure of a truly great man is the courtesy with which he treats lesser men.

Courtesy should be a continuous action, not something to be turned on and off like a faucet.

Life is short, but there is always time for courtesy.

Men, like bullets, go farthest when they are smoothest.

Courtesy Life be not so short but that there is always time for courtesy.

If a man be gracious and courteous to strangers, it shows he is a citizen of the world.

Intelligence and courtesy not always are combined; Often in a wooden house a golden room we find.
