You know what surprised me about these folks? That they responded, at first, with a "yes I'll take them in". Almost any such thing done in the states would be swiftly rebuffed.
I have to admit though, being ambushed by having a guy RIGHT THERE to be taken in - as magnanimous as I might be about say, taking in a Ukrainian refugee, I have a crowded home with children, and I'd have to plan first.
My parents DID do something like this - took in a whole family from Panama when Noriega was there - but admittedly, they at first took in just one person, and that when no one else was living at home with them.
