Friendship is always a sweet responsibility, never an opportunity.

As iron sharpens iron, so a friend sharpens a friend.

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

The friend is the man who knows all about you, and still likes you.

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

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

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

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

A true friend is the greatest of all blessings, and that which we take the least care of all to acquire.

Peace and friendship with all mankind is our wisest policy, and I wish we may be permitted to pursue it.
