Fausto, I have host three of my grandparents. The harestimated one was the first to go. He died unexpectedly, and my grandma had to face being alone. That was 22 years ago, and mygrandma is still with us. She is 100.
My other grandpa suffered from advanced Alzheimers, and my grandma (his wife ) was completely ready to be done with this life. So we had time to prepare. Their funerals were more sweet, and much less sad.
I just buried my young brother in law this summer. That was a much more traumatic event for his family. His death was suicide, at 32. It happened while we were visiting for vacation, on my birthday. That event was much more sorrow filled than most funerals I've been part of.
I take a pretty wide open view about death. Death is a part of life. It can be easier or harder to deal with depending on the circumstances. But we all get to deal with it at some point.
Hopefully your experience with your grandfather's passing is tempered with sweetness and pleasant memories. I know my own grandparents are remembered with laughter, and fond memories. My only regreta involve not knowing them as well as I might have, if I had been older, and lived closer.
I'd be happy to carry that yellow rose knife, if luck brings it across the pond.
