Babycakes, I just wanted to echo Steve's sentiments. I took care of both of my parents before they passed and I know how physically and emotionally taxing it can be, no matter how much you love them. I know it took a toll on me, but I would do it again in a heartbeat.
I hope all goes well with your Pop. I'll be sending some good thoughts your way on Friday. Take care and God Bless, CMP/MM
