I am always wary about these stories about loving devoted parents deserted by selfish children.
There are always two sides to stories like this. Every neglected parent will tell the story of their devotion to their children, how they did everything for them etc etc, but quite often if you have a chance to look any deeper, you find it is not quite that simple and often the parent/child relationship has never been good, the parent is nowhere as wonderful as they say they were.
I worked for what is now Age UK as a volunteer home visitor for 10 years and visited hundreds of old people. I remember visiting a very elderly man, recently widowed, with six children, none of whom could look after him. I visited this poor old man wracked by grief, describing how much he loved and missed his wife, describing the perfect marriage relationship and how proud he was of his children.
A few months later I visited another client on the same estate. As she answered the door, she looked over my shoulder to an elderly man walking past and said 'Oh, there's that horrible Mr Smith', Looking to the road, I saw my devastated widower client. As we walked into the house my new client commented. 'Nobody likes him, he used to beat up his wife and kids. They chucked him out of the pub recently because he threatened someone with his walking stick.
As I said, I am wary about these tragic tales of loving parents deserted by their children.
