I am so sorry for your loss Z.
I lost my grandad only a few months ago too.
He too was taken away from us by cancer at 85.
I didn't even get a chance to say goodbye because I live in the States.
I will always remember him with love and respect. He lived in our home for 13 years in Italy and when I moved away to the States I really hoped that I would be able to see him again. I will always have a lot of fun memories of him. He taught me a lot in life.
I know that you and your family must be going through a tough time now but try to celebrate his life instead of being sad for his death. I am sure that is what he would have wanted.
hugs
