After that, my mind continued to clench on the image of the old man wearing the barber’s pan on his head and thinking it was a golden helmet. At first, I thought it was ludicrous and then I thought it was sad. I was thinking that normal people seem to see things pretty clearly. Then it occurred to me that about half the time I don’t know whether I understand what I’m seeing or not. I was wondering if everybody is as confused as I am, if maybe I have a pan on my head and just don’t know it.
