"What, sir, to say nothing more, can one be forever dealing in macassar oil, hair dyes, cosmetics, false moustaches, wigs, and toupees, and still believe that men are wholly what they look to be? What think you, sir, are a thoughtful barber's reflections, when, behind a careful curtain, he shaves the thin, dead stubble off a head, and then dismisses it to the world, radiant in curling auburn? To contrast the shamefaced air behind the curtain, the fearful looking forward to being possibly discovered there by a prying acquaintance, with the cheerful assurance and challenging pride with which the same man steps forth again, a gay deception, into the street, while some honest, shock-headed fellow humbly gives him the wall! Ah, sir, they may talk of the courage of truth, but my trade teaches me that truth sometimes is sheepish. Lies, lies, sir, brave lies are the lions!" (43, 14)
Talk about disillusioned. Years of helping people cover up perceived flaws within the beauty industry has left the barber feeling like no one's the real deal. This kind of distrust breeds misanthropy, because thinking everyone is fake makes it kind of hard to make friends. The barber's also kind of judgmental for someone who's trusted with other people's secrets.
