@Diane,
I've had a similar reaction all day today, much like I did during my father's illness. Doesn't make a bit of sense since I've never met Bob face to face, but sometimes I feel like I know him better than I knew my own dad. They're both very gentle souls with a gruff exterior to mask the mushmellows inside.
I wish I was able to be there with you, Diane. Frustratingly, all I can do is gather some good memories and thoughts to encircle you with warmth and comfort.
