Friendship is always a sweet responsibility, never an opportunity.

Friendship is something that creates equality and mutuality, not a reward for finding equality or a way of intensifying existing mutuality.

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

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

When the world is so complicated, the simple gift of friendship is within all of our hands.

He has no enemies, but is intensely disliked by his friends.

Depth of friendship does not depend on length of acquaintance.

Friendship is always a sweet responsibility, never an opportunity.

A friend may well be reckoned the masterpiece of nature.

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