We all see what we want to see. Very few of us (myself excluded) can see what is there, if we don't expect it. I find this particularly annoying in Call Centre staff. But then I remind myself, could I do any better, relying on just a voice on a poor phone line?
We all know the stories, from our childhood. They were told to us to illustrate and teach us a good moral centre. Stories like, The Boy Who Cried Wolf, The Ugly Duckling, and The Emperor's New Clothes.
