My maternal grandfather died in WW1. My maternal grandmother's house was destroyed in the blitz and for my first 4 years she live with us, then moved back to her own house. I loved her deeply, she was on the same wave length as me, which my parents, much as they loved me, weren't.
I had several long spells in hospital, in London, when my parents lived in Carlisle and after the first one, when I came out I spent a week living with her, just the two of us and I remember it as being one of the happiest weeks of my childhood. After that I always insisted that any long hospital stay should be followed by spending a week with her.
My paternal granparents were very different. I found my grandfather quite remote. He was an army officer, rising through the ranks and an eminent catholic layman, so he was out of the house a lot, and in his study a lot when in and usually only apppeared towards the end of each visit.My paternal grandmother did not like my mother, who was pretty and vivaceous and went to the opera and ballet and loved nice clothes, and that carried over to me, as I was thought to be too much like my mother, although why I do not know, but i was opinionated (nothing has changed) and I had a perfectly normal teenage interest in clothes and how I looked.
