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

Friendship without self-interest is one of the rare and beautiful things of life.

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

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

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

One of the most beautiful qualities of true friendship is to understand and to be understood.

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

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

If you have one true friend you have more than your share.

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