hmmmmm well I've only had one done, he took a bit of jewelry and then gave a reading..he was quite a well known one although can't for the life of me remember his name.
He didnt know that me and mum were related - and when we spoke about our readings after they were SO similar - and we listened to each others tape recording that was £10 extra - and there were things said in both that were apparently going to happen to both of us, or the same persons name came up (but not the kind of thing mother and daughter would experience together if that makes sense)
