The Scandal Detectives by F. Scott Fitzgerald

It was a hot afternoon in May and Mrs. Buckner thought that a pitcher of fruit lemonade might prevent the boys from filling up on ice cream at the drug store. She belonged to that generation, since retired, upon whom the great revolution in American family life was to be visited; but at that time she believed that her children's relation to her was as much as hers had been to her parents, for this was more than twenty years ago.

Some generations are close to those that succeed them; between others the gap is infinite and unbridgeable. Mrs. Buckner -- a woman of character, a member of Society in a large Middle-Western city -- carrying a pitcher of fruit lemonade through her own spacious back yard, was progressing across a hundred years. Her own thoughts would have been comprehensible to her great-grandmother; what was happening in a room above the stable would have been entirely unintelligible to them both. In what had once served as the coachman's sleeping apartment, her son and a friend were not behaving in a normal manner, but were, so to speak, experimenting in a void. They were making the first tentative combinations of the ideas and materials they found ready at their hand -- ideas destined to become, in future years, first articulate, then startling and finally commonplace. At the moment when she called up to them they were sitting with disarming quiet upon the still unhatched eggs of the mid-twentieth century.
