Friendship
The Artist has little difficulty in recognising The Showman.
The Showman, by contrast, has great difficulty in recognising The Artist.
It takes all the courage of The Artist to extend the hand of friendship to The Showman, and it takes all the courage of The Showman to reciprocate.
This is why such a friendship so rarely forms.
But, every once in a while, this friendship is formed, and humanity advances to a new level.
