Soweto resident Joy Chauke pauses as she lays flowers outside the old house of Nelson Mandela 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&#039;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.
