It started out bad Ron, given the circumstances, it sounds like it is ending with a lot of reflection and thanks for having what is really so important to us all--our family! Knowing that your father did well in this ordeal is a tremendous relief for you - and also for us! I also send my prayers and best wishes for your father's speedy recovery and for the rest of your family.
And BTW, I guaranty that firm handshake of yours with a heartfelt "Thank you" to the surgeon probably made his day as well. No expression of thanks and gratitude from the heart is ever a petty thing. That kind of thank you is what keep many in the Emergency health field (on every level) going when things get overwhelming and full of despair.
