Grandfather (Thoughts, Prayers, and advice)

I know many of you guys don't know me too well since I've been a sporadic member. However I am hoping to get some thoughts, prayers, and even advice since my Grandfather is in the hospital and it looks like his time could be coming to an end. It's not a surprise since his health has been in great decline the last five years. But today while working on the Dart a memory of him helping me install the leaf springs struck me pretty hard and I actually teared up quite a bit. For those of you guys who have lost a Father/Grandfather how did you guys cope with the memories that seem to flood a person during these times?
