I don't get it. If one is homeless then why not just get a home and cease to be homeless?
The bobbling one has just decided to be homeless/helpless and could just as easily decide not to be either anymore.
Lots of people have been homeless and then stopped being homeless.
Everybody is, more or less, what they have decided to be. Even people who have great misfortune befall them, some decide to be victims and some decide to deal.
