[1] It was still too hot to play outdoors. They had had their tea, they had been washed and had their hair brushed, and after the long day of confinement in the house that was not cool, but at least a protection from the sun, the children strained to get out. Their faces were red and bloated with the effort, but their mother would not open the door, everything was still curtained and shuttered in a way that stifled the children, made them feel that their lungs were stuffed with cotton wool and their noses with dust and if they didn't burst out into the light and see the sun and feel the air, they would choke.
