Their husbands were among the 34 striking miners gunned down by the police in the infamous "Marikana massacre" outside a platinum mine in the North West province town, the worst such incident since the end of apartheid.
"Mama why did the police kill my father?" asks Ngweyi's son, to which she has no answer.
The 10th anniversary of the killings is also being commemorated in "Marikana the Musical", being performed in Pretoria, in which people dressed as miners and police re-enact the tragedy as sombre music plays in the background.
To the audience and actors alike, the violence is incomprehensible. Lead actor Mavuso Magabane said: "Every night before I come on stage I watch the videos, I relive the moment so that when I come on this stage I'm in a trance."
