Friendship may, and often does, grow into love, but love never subsides into friendship.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

Am I not destroying my enemies when I make friends of them?

Mighty proud I am that I am able to have a spare bed for my friends.

Friendship is the shadow of the evening, which increases with the setting sun of life.

A man's growth is seen in the successive choirs of his friends.

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.

Caring for but never trying to own may be a further way to define friendship.

Peace and friendship with all mankind is our wisest policy, and I wish we may be permitted to pursue it.
