When we invited my Nan to come and live with us because she could no longer manage by herself we were pleased that we did have the room so that she could have her own living room and watch what she wanted to watch, have her space and do what she liked.
What we hadn't counted on was that after years of living alone what she really longed for was the company of her family. I cannot once remember Nan going to use this space for herself. We however as teenagers also wanted our own space and would frequently find a quiet corner of the house. Perhaps if Garages should be converted it should be for the kids and not the grandparents?
I look back now with sadness that the view of a fifteen year old teenager is blinkered at the time, seeing older grandparents as an inconvenience. She was a lovely lady and was so kind. Despite a rota of aunts to help out with her care at our home, she eventually needed more permanent care as dementia took its course.
