Real friendship, like real poetry, is extremely rare - and precious as a pearl.

Friends and good manners will carry you where money won't go.

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

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.

A friend may well be reckoned the masterpiece of nature.

To like and dislike the same things, this is what makes a solid friendship.

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.

A man cannot be said to succeed in this life who does not satisfy one friend.

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