Never explain - your friends do not need it and your enemies will not believe you anyway.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

Friendship multiplies the good of life and divides the evil.

One of the most beautiful qualities of true friendship is to understand and to be understood.

It is more shameful to distrust our friends than to be deceived by them.

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

A friend may well be reckoned the masterpiece of nature.

Real friendship, like real poetry, is extremely rare - and precious as a pearl.

Be true to your work, your word, and your friend.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.
