'A man that looks on glass,
On it may stay his eye;
Or if he pleaseth, through it pass,
And then the heav'n espy.'
The Elixir by George Herbert
The clown looks into a mirror, on the other side is a smartly dressed businessman in an immaculate suit and bowler hat.
The clown sees his reflection - a bedraggled, ridiculous figure, humbling himself every night so people can laugh at him, earning a pittance. Through the glass he sees the smart wealthy businessman, a figure of respect that he longs to be.
The businessman sees in his reflection a dull, straight laced, number cruncher who lives in the straight jacket of conservative conventions and mores. Looking through the glass he longs to be anarchic, irresponsible and amusing as he imagines the
clown to be.
