Yes, I have got that figured out - Peter likes to talk about alot of things and that's OK by me - he needs someone to just relax with and chat with too.  I'm totally OK with that ! After awhile, I usually gently pull him back to a question I want him to answer and that works. I want Peter to feel free to talk and I know he will answer my question when we get  around to it again. We must have chatted for a couple of hours today and was quite enjoyable and reassuring
