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

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

Walking with a friend in the dark is better than walking alone in the light.

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

Wishing to be friends is quick work, but friendship is a slow ripening fruit.

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

Think where man's glory most begins and ends, and say my glory was I had such friends.

I have friends in overalls whose friendship I would not swap for the favor of the kings of the world.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

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