(CNN) -- Tracy Orr sat in the back of the room and prepared to watch her foreclosed home go up for auction this past Saturday. That's when a pesky stranger sat down beside her and struck up a conversation. Tracy Orr faced losing her home to foreclosure when Marilyn Mock, a stranger, stepped in to buy it."Are you here to buy a house?" Marilyn Mock said. Orr couldn't hold it in. The tears flowed. She pointed to the auction brochure at a home that didn't have a picture. "That's my house," she said.
Within moments, the four-bedroom, two-bath home in Pottsboro, Texas, went up for sale. People up front began casting their bids. The home that Orr purchased in September 2004 was slipping away.
