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

Friends show their love in times of trouble, not in happiness.

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

Friendship, of itself a holy tie, is made more sacred by adversity.

Men kick friendship around like a football, but it doesn't seem to crack. Women treat it like glass and it goes to pieces.

Friendship, like the immortality of the soul, is too good to be believed.

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

Friendship is always a sweet responsibility, never an opportunity.

You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

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