Blinded
I know everyone is familiar with Superman, and his alter ego, Clark Kent. One of the late night television shows did a spoof on this once. Clark Kent is sitting at his desk at the Daily Planet, and he takes his glasses off to rub his eyes, and someone yells out, “Superman! Wow! When did you get here!” And Clark puts his glasses back on to look around for Superman, and the person goes, “Huh? Where did he go? He was just here!” Clark gets wise, and pulls his glasses off again, and the person yells, “Oh! There you are!” What follows is Clark Kent taking his glasses off and on, with people seeing Superman, and then suddenly blinded to his presence the moment Clark puts his glasses back on. They thought Clark kind of looked like that Superman guy, but obviously, Superman didn’t need glasses, so it couldn’t possibly be him. They doubted what was right in front of them, and so they were blinded to reality.
