The world of the homeless seems very far from yours -- but in some ways it is quite near. For any of us, the loss of a job, the death of a spouse or a child or a severe physical disability could be the route to total despair. These are the very tragedies that have happened to many homeless people. Struck by personal tragedies, the people in shelters across America, have lost their homes and been deserted by the families and friends they once had. What can you do to help them? Sometimes the smallest can go a long way.
