What's wrong with that? Because these folks experienced the "best outcome" (presumably to see their parents live to old age) they shouldn't get emotional about it?
The top-level response in question is disgusting. It's like listening to someone who won a million dollars in a lottery complain that they didn't win ten millions. Should I really feel compassionate towards a "victim" of such a bad luck of only winning a single million? Even if the "victim" genuinely feels bad about themselves?
you're characterizing them as ungrateful, which isn't really coming across for me at all.
That's a straight-up lie. Read the comments here. People declaring themselves miserable are asking for compassion.
