I must admit, I once met one who impressed me. He was the manager of a pub we'd never been to before, and which was a very long way from our home. He just came to our table and said 'I have something to tell you'. He said a lot about my grandmother, who died before I was born, and none of it made any sense at all to me. In fact I thought it quite amusing because it was all such gobbledegook. However, when I went home and asked my father if any of it meant anything to him, he was absolutely astonished and understood it all completely. This man didn't do it for a living, he didn't do readings, and neither was he religious - but he certainly knew more about my ancestors than I did - and he told me things - specific and unusual things - that he couldn't possibly have gleaned from me, because I didn't know about them. Me being me, I needed to know how this worked, and he told me there's nothing mysterious about it at all. He said some people have the ability to tune their minds, and it's just like tuning a radio. Now I know you're going to poo poo this, Chakka, old chap - but so be it. That's what happened, and I have no logical explanation for it other than to say that some people do possess abilities that the rest of us don't.
