In all honesty probably no, but then again I am sure some homeless people are quite stubborn and would they really want to go to a strangers house anyway?, a lot are quite happy doing what they are doing with the people they know on the street. They might be frightened of all sorts of things, i.e. getting changed by the people they are with and just suppose something happened, it would be them that got blamed for it wouldn't it? I say leave well alone and help out in the hostels and put up soup kitchens, safer that way!
