We call them the homeless, as if they’re all alike and their entire lives can be reduced to a single descriptive word. Thousands, hundreds of thousands, up to half a million people in America may not know precisely where they’re going to sleep tonight or where their next meal will come from. A woman named Peggy is one such person. She has slept in parks and on the streets. She has eaten at free kitchens. She has a story. And she has pride, as well as dreams and goals. She joins Michael Glab on this week’s edition of Big Talk.
