Never have a companion that casts you in the shade.

True friendship ought never to conceal what it thinks.

A single rose can be my garden... a single friend, my world.

The best time to make friends is before you need them.

Our friends interpret the world and ourselves to us, if we take them tenderly and truly.

A man's friendships are one of the best measures of his worth.

It is not so much our friends' help that helps us, as the confidence of their help.

That friendship will not continue to the end which is begun for an end.

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

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