Burger’s Daughter by Nadine Gordimer
Among the group of people waiting at the fortress was a school-girl in a brown and yellow uniform holding a green eiderdown quilt and, by the loop of its neck, a red hot-water bottle. Certain buses used to pass that way then and passengers looking out will have noticed a schoolgirl. Imagine, a schoolgirl: she must have somebody inside. Who are all those people, anyway? Even from the top of a bus, lurching on past as the lights go green, the group would not have looked like the usual prison visitors, passive and self-effacing about the slope of municipal grass.
