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

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

My best friend is the one who brings out the best in me.

Be slow to fall into friendship but when thou art in, continue firm and constant.

But friendship is the breathing rose, with sweets in every fold.

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

Friendship is always a sweet responsibility, never an opportunity.

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

Friendship multiplies the good of life and divides the evil.

Friends and good manners will carry you where money won't go.
