A 51-year-old lawyer has moved back in with his mother-after giving up his Los Angeles  home to a family of strangers for a year. Tony Tolbert looked for a family in need after his father set a glowing example when he was growing up by always welcoming people to stay in their spare room. "You don't have to be Bill Gates or Warren Buffet or Oprah," Tolbert told CBS.  "We can do it wherever we are, with whatever we have, and for me, I have a home that I can make available. " His mother, Marie Tolbert, added,  " He is go giving,  and he's always been that way. " Tolbert went to Alexandria House, a shelter for homeless women and children, and came across Felicia Dukes, who lived in a single bedroom with three of her children.  Her family had been separated as the shelter was just for children and her eldest son was unable to join them. Tolbert told the staff he wanted to bring the. family back together, and offered his home.  The family has now moved into the three-bedroom, two-bathroom home - with Duke's oldest son. It is worth nearly $400,000, according to online estimates.  "My heart just fills up with appreciation, "  Dukes said, as she wiped away her tears.
