I urged Joan to read the chapter in The Book Of Joan about when Joan first hears the voices talking to her. I'm not sure she took much from it, despite my subsequent inquisition but she was very polite. Hopefully she ignored all the skin cutting and grafting which I found frankly disturbing though this was probably the point. Then I rushed the fearsome book back to a charity shop. So both Shelter from whence it was purchased and now dear Oxfam should profit from our limited education.
