There is genuinely little more heartbreaking than a wee tyke of four using his limited breath & energy to send you a voice message thanking you for saving his life.

It's not a Hallmark feel-good moment.
It's right up there with "2nd grader pays off his schoolmates' lunch debt".

In a just society that little boy wouldn't have to be grateful to anyone for stepping in, because his family wouldn't have been stepped *on* in the first place. Poor little guy. I hope he finally gets to be a kid again.
