As iron sharpens iron, so a friend sharpens a friend.

Friendship is something that creates equality and mutuality, not a reward for finding equality or a way of intensifying existing mutuality.

The friend is the man who knows all about you, and still likes you.

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

The language of friendship is not words but meanings

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

Friendship multiplies the good of life and divides the evil.

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

A friendship that like love is warm A love like friendship, steady.

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