In case anyone is interested, Radio 4's The Archers currently has a storyline running of a widow Carol Tregorran (sp?) with a daughter who lives far away. The daughter is trying to get her Mum to accept more external help but is being met with intransigence. It is interesting listening to both points of view.
As a compare and contrast they are also following Bert Horrobin who lives with his daughter and her family, with other close family nearby, and everyone rallying around.
