There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Friendship is a plant of slow growth and must undergo and withstand the shocks of adversity before it is entitled to the appellation.

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

Friendship is always a sweet responsibility, never an opportunity.

Friendship, like the immortality of the soul, is too good to be believed.

An insincere and evil friend is more to be feared than a wild beast a wild beast may wound your body, but an evil friend will wound your mind.

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

Friendship is the shadow of the evening, which increases with the setting sun of life.

The friend is the man who knows all about you, and still likes you.

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