inishowen Your account of your granny coming to live in your family struck a chord with me.
About 15 years ago we thought of buying a bigger house for my husband and I and my Mum, using the proceeds of sale of our own and my Mum's house (with our respective financial contribution being protected by a legally drawn up contract). Although Mum would have been contributing considerably less money than us, she expected to requisition all the largest rooms in the houses we viewed and stated that she wished to keep all her furniture. In the end we decided it could never work, with such a demanding and uncompromising attitude.
With hindsight, I realise it was a stupid thing to even contemplate although I can see that it very much depends on the people involved. My Mum is quite manipulative and very demanding. When she comes to stay for a week or two at Christmas and other times of the year, she wants the TV on, blaring loudly, all day, she is very possessive, won't stay in the house on her own so has to come everywhere with my husband and I, and keeps me running around all the time. By the end of her visit, I am exhausted and stressed.
She is now in her late 90's, is (touch wood) healthy apart from poor eyesight and hearing and has plenty of capital to live comfortably at home - meals on wheels, someone to do the garden, shopping, cleaning etc. (though she is reluctant to pay people properly), and I spend 6 hours a day every week travelling in order to visit her. Also a nearby friend of hers visits every week. Still she complains that "nobody bothers about the elderly these days".
It has been hinted at by her neighbours that we should take her into our home but I think it would wear me into the ground and cause problems between myself and my husband. Needless to say, the people who have proposed this arrangement for us have never shared their home with a parent.
