hard to believe this is true, I'm in Toronto and some of the dark corners of US society are alien....but it's just sad. And I shouldn't have spent too much time reading the comments on here about hypothetical not-helping scenarios etc. sigh. Tough situation/sad.
I mean, this is an aspect of human nature that's been pretty well documented for decades, at least. It might make you uncomfortable, but it's also not some unusual, hard-to-believe example of how "the dark corners of US society are alien".
