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

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

Our friends interpret the world and ourselves to us, if we take them tenderly and truly.

Let there be no purpose in friendship save the deepening of the spirit.

It is important to our friends to believe that we are unreservedly frank with them, and important to friendship that we are not.

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

Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.

Friendship without self-interest is one of the rare and beautiful things of life.

When the world is so complicated, the simple gift of friendship is within all of our hands.

Friendship multiplies the good of life and divides the evil.
