Things Fall Apart

From the text:

Ekwefi went into her hut to cook yams. Her husband had brought out more yams than usual because the medicine man had to be fed. Ezinma went with her and helped in preparing the vegetables.

"There is too much green vegetable," she said.

"Don't you see the pot is full of yams?" Ekwefi asked. "And you know how leaves become smaller after cooking."

"Yes," said Ezinma, "that was why the snake-lizard killed his mother."

"Very true," said Ekwefi.

"He gave his mother seven baskets of vegetables to cook and in the end there were only three. And so he killed her," said Ezinma.

"That is not the end of the story."

"Oho," said Ezinma. "I remember now. He brought another seven baskets and cooked them himself. And there were again only three. So he killed himself too."
