Politeness: The most acceptable hypocrisy.
Ambrose Bierce (1842-1914) American newspaperman and short-story writer.
Politeness is to human nature what warmth is to wax.
Arthur Schopenhauer (1788-1860) German philosopher.
To find out what others are feeling, don't prod or poke. If you want play with a turtle, you can't get it to come out of its shell by prodding and poking it with a stick, you might kill it. Be gentle not harsh, hard or forceful.
