If you would keep your friend, approach him with a telescope, never with
the microscope.

--_Anon_.

It is one of the severest tests of friendship to tell your friend of his
faults. If you are angry with a man, or hate him, it is not hard to go
to him and stab him with words; but so to love a man that you cannot
hear to see the stain of sin upon him, and to speak painful truth
through loving words--that is friendship. But few have such friends. Our
enemies usually teach us what we are, at the point of the sword.

--_Beecher_.

My friend is not perfect--no more I--and so we suit each other
admirably.

--_Pope_.

I could not live without the love of my friends.

--_John Keats_.

It is a good thing to be rich, and a good thing to be strong, but it is
a better thing to be beloved of many friends.

--_Euripides_.
