I had not known this story until I heard the sister in a lengthy BBC interview in the middle of the night a year or so ago. I was mesmerized. (Unfortunately, as anyone who has ever heard something on the beeb and tried to find a podcast to listen again knows, it is an amazingly frustrating, nearly hopeless task. Considering how much content they generate and their long-term stature as broadcaster to the world, it is amazing how "a. retentive" they are about making their material publicly available after it has been broadcast.)

(It is not allowed, in this forum, to use the anatomical term beginning with "a" which is widespread in the psychological and psychiatric literature to describe the personality type which seeks to hold onto things in an ungenerous way.)
