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

That friendship will not continue to the end which is begun for an end.

Depth of friendship does not depend on length of acquaintance.

Laughter is not at all a bad beginning for a friendship, and it is far the best ending for one.

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

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

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

Friendship is a strong and habitual inclination in two persons to promote the good and happiness of one another.

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

Friendship is always a sweet responsibility, never an opportunity.
