I am sorry for your loss. My Dad's name was Bob too. Same thing, I could have written what you wrote myself, word for word, right to the very end. I was with my Dad, holding his hand when he passed away this October 2nd.

Dad just turned 71. I too have had spinal surgeries and need of a lumbar fusion.
Hospice was wonderful and a Godsend. I too am going to volunteer when I can, to sit and help others in their time of need.
Dad's last 4 hours were the hardest for Me and my Family. I can sympathize with you. My Condolences on your loss.
Lori
