Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

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

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

A quarrel between friends, when made up, adds a new tie to friendship.

A true friend never gets in your way unless you happen to be going down.

A true friend is one who overlooks your failures and tolerates your success!

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

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

A friendship that like love is warm A love like friendship, steady.

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.
