A friendship founded on business is better than a business founded on friendship.

Friendship is a plant of slow growth and must undergo and withstand the shocks of adversity before it is entitled to the appellation.

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

One of the most beautiful qualities of true friendship is to understand and to be understood.

Never explain - your friends do not need it and your enemies will not believe you anyway.

I don't need a friend who changes when I change and who nods when I nod my shadow does that much better.

No person is your friend who demands your silence, or denies your right to grow.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

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

True friendship ought never to conceal what it thinks.
