My grandmother Mavis died yesterday morning after a short illness. Her last words were 'can I go now?'*
I was close to her particularly in the 1960s as she looked after me a lot then the take-home message from those days as relayed to me was her trying to stop me running into everyone's driveway. It is very sad to see her go, but we were certainly all aware that she was hoping to go, with her faculties essentially intact, and not a nuisance to anyone. She did not need glasses to read the paper.
*I'm creating a myth here, or trying to. She said some other things, I've been told, on the same general topic and this encapsulates the sentiment.
