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

It is more shameful to distrust our friends than to be deceived by them.

Friendship is always a sweet responsibility, never an opportunity.

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

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

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

Never contract friendship with a man that is not better than thyself.

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

One's friends are that part of the human race with which one can be human.

Cherish your human connections: your relationships with friends and family.
