You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

Friendship is certainly the finest balm for the pangs of disappointed love.

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

Mighty proud I am that I am able to have a spare bed for my friends.

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

If you have one true friend you have more than your share.

Depth of friendship does not depend on length of acquaintance.

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

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.

Caring for but never trying to own may be a further way to define friendship.
