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

A friendship founded on business is better than a business founded on friendship.

Think where man's glory most begins and ends, and say my glory was I had such friends.

My best friend is the man who in wishing me well wishes it for my sake.

Friendship multiplies the good of life and divides the evil.

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

The sincere friends of this world are as ship lights in the stormiest of nights.

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

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

Instead of loving your enemies - treat your friends a little better.
