I think they will do what they want to do, whether its attend charities in Canada, or skeet shooting.. or - staying home with Archie. I don't think they are to be relied on for anything except that they will do what they want to do. But IMO they don't have the money they will need for the kind of life they want - so its not likel they could live a quiet life, comfortable and rich and doing a bit of private charity work... they will have to hunt for more money...
