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

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

My best friend is the one who brings out the best in me.

To like and dislike the same things, this is what makes a solid friendship.

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

The language of friendship is not words but meanings.

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

A man cannot be said to succeed in this life who does not satisfy one friend.

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

Friendship, like the immortality of the soul, is too good to be believed.
