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

Friendship, of itself a holy tie, is made more sacred by adversity.

Let there be no purpose in friendship save the deepening of the spirit.

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

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

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

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