I don't think there's anything sadder in the world than an ill child. I mean you might have some serious issues if you can't sympathize with a sick kid. I feel bad for afflicted adults, but because kids are so un-bogged down by the typical BS that adults get themselves into, I just find that my heart goes out to them more than any grown-up.
But that doesn't mean adults can't be awesome, either.
Like this babysitter who, was a nanny to little Talia Rosko for only three weeks before discovering the baby had a life-threatening liver disease.
