"A creaking of the kind made by the weight carried by one foot after another along a wooden floor. I listened. I felt the apertures of my ears distend with concentration."
"pure concentration camp style."

"Once upon a time" is a stock phrase used to introduce a narrative of past events, typically in fairy tales and folk tales. It has been used in some form since at least 1380 in storytelling in the English language and has started many narratives since 1600. These stories sometimes end with "and they all lived happily ever after", or, originally, "happily until their deaths".
"A creaking of the kind made by the weight carried by one foot after another along a wooden floor. I listened. I felt the apertures of my ears distend with concentration."
"I have no burglar bars, no gun under the pillow. But I have the same fears as people who do take these precautions, and my windowpanes are thin as rime, could shatter like a wine glass."
"But I learned that I was to be neither threatened nor spared. There was no human weight pressing on the boards, the creaking was a buckling, an epicenter of stress. I was in it."
"It was not possible to insure the house, the swimming pool or the car against riot damage. There were riots, but these were outside the city, where people of another color were quartered. These people were not allowed into the suburb except as reliable housemaids and gardeners, so there was nothing to fear, the husband told the wife. Yet she was afraid that some day such people might come up the street and tear off the plaque YOU HAVE BEEN WARNED and open the gates and stream in... Nonsense, my dear, said the husband, there are police and soldiers and tear-gas and guns to keep them away."
"The man and his wife, talking of the latest armed robbery in the suburb, were distracted by the sight of the little boys pet cat effortlessly arriving over the seven-foot wall, descending first with a rapid bracing of extended forepaws down on the sheer vertical surface, and then a graceful launch, landing with swishing tail within the property."
"I reply that I don’t write children’s stories; and he writes back that at a recent congress/book fair/seminar a certain novelist said every writer ought to write at least one story for children. I think of sending a postcard saying I don’t accept that I ‘ought’ to write anything."
