Where minds differ and opinions swerve, there is scant a friend in that company.

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.

A friend should be a master at guessing and keeping still: you must not want to see everything.

Shared joys make a friend, not shared sufferings.

Go up close to your friend, but do not go over to him! We should also respect the enemy in our friend.

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.
