A well-wisher writes a message on a poster of Nelson Mandela on which she and others have written their messages of condolence and support, in the street outside his old house in Soweto, Johannesburg, South Africa Friday, Dec. 6, 2013. Flags were lowered to half-staff and people in black townships, in upscale mostly white suburbs and in South Africa’s vast rural grasslands commemorated Nelson Mandela with song, tears and prayers on Friday while pledging to adhere to the values of unity and democracy that he embodied.
