True friendship can afford true knowledge. It does not depend on darkness and ignorance.

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

There is nothing on this earth more to be prized than true friendship.

A friend may well be reckoned the masterpiece of nature.

I always felt that the great high privilege, relief and comfort of friendship was that one had to explain nothing.

Love is flower like Friendship is like a sheltering tree.

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

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

Friendship is the source of the greatest pleasures, and without friends even the most agreeable pursuits become tedious.

Depth of friendship does not depend on length of acquaintance.
