Friendship is always a sweet responsibility, never an opportunity.

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

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

Friends... they cherish one another's hopes. They are kind to one another's dreams.

A friendship founded on business is better than a business founded on friendship.

There is nothing on this earth more to be prized than true friendship.

A man's friendships are one of the best measures of his worth.

I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar.

Friendship is the shadow of the evening, which increases with the setting sun of life.

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