30 years ago there were places kids to run to if they were worried about a stranger. These days, many don’t want to be involved.
I do recall (this would have been quite a few years ago tho) a program in which parents who were willing to be a place kids could go in case of emergency had signs in their windows. I don’t recall what, if any, sort of background checks were done, tho.
It’s sad that we don’t all know our neighbors anymore. But, even when I was growing up, I doubt I would have gone to anyone else’s house in case of emergency. I would have felt weird. I’m sure I would have hoofed it home. Of course, back then we were all in great shape from walking/running all over the place.
