I always felt that the great high privilege, relief and comfort of friendship was that one had to explain nothing.

True friendship can afford true knowledge. It does not depend on darkness and ignorance.

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

The greatest sweetener of human life is Friendship. To raise this to the highest pitch of enjoyment, is a secret which but few discover.

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

Be slow to fall into friendship but when thou art in, continue firm and constant.

It is important to our friends to believe that we are unreservedly frank with them, and important to friendship that we are not.

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

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Friendship is a strong and habitual inclination in two persons to promote the good and happiness of one another.
