Since there is nothing so well worth having as friends, never lose a chance to make them.

A true friend never gets in your way unless you happen to be going down.

Depth of friendship does not depend on length of acquaintance.

A quarrel between friends, when made up, adds a new tie to friendship.

A true friend is someone who is there for you when he'd rather be anywhere else.

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

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

Walking with a friend in the dark is better than walking alone in the light.

Am I not destroying my enemies when I make friends of them?

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