Under the heavens and under the sea there's a friend I don't know, who holds the right key.

The only service a friend can really render is to keep up your courage by holding up to you a mirror in which you can see a noble image of yourself.

You meet people who forget you. You forget people you meet. But sometimes you meet those people you can't forget. Those are your friends.

Don't expect your friend to be a perfect person. Help your friend to become a perfect person. That is true friendship.

Oh my only friend, my best beloved, the gates are open in my house-do not pass by like a dream.

There is no possession more valuable than a good and faithful friend.
