Just last week, she was in Kou-kamma, moving from voting station to voting station for the by-election that took place there."He said she had an incredible work ethic."Even when she went for chemotherapy, she never took the day off, but would first come to the office or return to her duties directly afterwards."She was a mentor to many of us and was very active on the ground.
