Dean,
Though i do not know you personally, i am still very sorry for your loss and my condolences go out to you and your family.
Whether you knew it was coming or you Were "ready" for it, you never really are, it still comes as the ultimate shock. You just have to stay stong my friend, remeber the good times.
Heres to your dad Dean. At least now he is pain free, and living a better life.
