Particularly this bit...
What broke the spell for me was, oddly, people swearing by my gift. Some repeat customers claimed I’d made very specific predictions, of a kind I never made. It dawned on me that my readings were a co-creation – I would weave a story and, later, the customer’s memory would add new elements. I got to test this theory after a friend raved about a reading she’d had, full of astonishingly accurate predictions. She had a tape of the session, so I asked her to play it.
The clairvoyant had said none of the things my friend claimed. Not a single one. My friend’s imagination had done all the work.
