Maureen stood by the lake. Suddenly the other children came running through the trees with sharp cries of excitement. They rushed up to the lake, leaning over the clear water, watching the crowds of tiny fish. Some children demanded loudly to go to the boats, but all at once those who had been left behind at the ice-cream stall (小摊) came running up to make some announcement or other, and they all left the water and dashed back the way they had come. With growing excitement, Maureen ran after them.

When she saw what had been run for, she stopped running. They were buying things again. The toy stall was open and they were crowding around it. Behind the stall a middle-aged woman was selling a great variety of small rubbish. She took money from the forest of small hands in exchange for little boats, plastic dolls, yellow pencils and rubbers, or anything. Maureen leaned against a tree, looking on. The idea of spending washed against her face like a strong current, trying to draw her in.

Nona Parker pushed out to the edge of the group and laid what she had bought on the ground so that she could see what money she had left in her white purse. Under Maureen's eyes lay a boat, a mouth organ, and little plates of doll’s food in coloured plaster—a brown load of bread, a joint of beef, a pink pudding—all tiny and terribly desirable. Maureen was so full of the wish for the things like that that she couldn't bear to look at them. She turned her head sharply. Her face against the tree, she shut her eyes and prayed eagerly for some money, for the price of a set of toy plates.

In a moment, she opened her eyes, but she didn't turn back to the stall. It was too painful to see the others buying whatever they wanted. She rubbed almost round the tree, her eyes on the ground. And there under her feet was a ten-pence piece.
