Main Street by Sinclair Lewis

She had lived in Washington for a year. She was tired of the office. It was tolerable, far more tolerable than housework, but it was not adventurous.

She was having tea and cinnamon toast, alone at a small round table on the balcony of Rauscher's Confiserie. Four debutantes clattered in. She had felt young and dissipated, had thought rather well of her black and leaf-green suit, but as she watched them, thin of ankle, soft under the chin, seventeen or eighteen at most, smoking cigarettes with the correct ennui and talking of "bedroom farces" and their desire to "run up to New York and see something racy," she became old and rustic and plain, and desirous of retreating from these hard brilliant children to a life easier and more sympathetic. When they flickered out and one child gave orders to a chauffeur, Carol was not a defiant philosopher but a faded government clerk from Gopher Prairie, Minnesota.
