@Ragman,
I like to think I'm reasonably bright. I don't think he's a scammer because he hasn't asked for help. We just both blog on the same site, and he talks about his homelessness when he writes.
I don't offer to help people where I am for two reasons:
1, I live just south of Detroit, in gang territory. People here can be genuinely scary, and you never know who might have a gun. Most people do, actually. Someone gets shot every other day. So inviting a stranger into my home is a bad idea.
2, there's no such thing as true homelessness here. Because the winters are deadly, there are big shelters who take in everyone, and large public apartment buildings where people who can't pay rent are placed.
So people here didn't really *need* help.
This guy spent the summer sleeping in a tent in the woods. His situation is comparatively desperate.
