There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

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

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

Since there is nothing so well worth having as friends, never lose a chance to make them.

Never contract friendship with a man that is not better than thyself.

But friendship is the breathing rose, with sweets in every fold.

True friendship is like sound health the value of it is seldom known until it is lost.

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

Lots of people want to ride with you in the limo, but what you want is someone who will take the bus with you when the limo breaks down.

Be true to your work, your word, and your friend.
