Alex, I am sorry for your loss and give thanks that you, your wife, her family, and your stepchildren find solace and comfort through shared memories and love of one another.This has been a tough week for all of us, it seems.
Mike B. - they cna do amazing things concerning strokes these days, hang in there and remember that hearing is the last faculty effected, so talking and singing to your dad will help. I will add your dad to my list, as well as you, and your family, Alex.
