Hm, I read McKean's acting the opposite way; I thought he looked guilty rather than compassionate. I think most people would like to know the last thing their parent said before they died was their name, whether they were in the room for it or not, but maybe that's just me. (As a practical matter, nobody can be at somebody's bedside 24/7, and there's no way to know when these things will happen. I don't think I would feel more than a twinge of guilt in a situation like that).
