I will fight to my last breath to keep life in my body and those of my loved ones, not hit them over the head with "everyone dies" simply because you are too - callous? - to comfort a friend.
Sympathy is an honest mercy.
Sugar-coating is at best a deferral and at worst a lie. There's a difference.
My father has a cat that is slowly dying from a heart condition. This cat is his favorite, and was the only thing that kept him sane when he was home alone and going through very dark days. We all know that Tommy is going to expire, that he needs a lot of help, that he's never going to be "all better". We *understand* this. There's no delusion there. But never do I go around saying, "Hey, how's that dying cat?" When I looked after Tommy for my father when he was away, I called every day to give updates, positive stories of holding him and talking to him and singing songs to him. It was a comfort to my dad. Domino wouldn't let anything happen to Tommy while Dad was away. And if Tommy did die, he would be with me, and not alone.
It matters to my Dad. It matters to me more than announcing the final end. I will put a positive angle on Tommy without idiocy for the sake of my father's frayed feelings. Some things are that important, and that in itself is honest.
And god help me if I EVER compare House to any living human being I know. That's such an extreme and unpleasant example I would never evoke it.
