A man dates his quitting smoking from a day on which he had gone to pick up his children from the city library.
A thunderstorm greeted him as he arrived there; and at the same time a search of his pockets disclosed a familiar problem: he was out of cigarettes.
Glancing back at the library, he caught a glimpse of his children stepping out in the rain, but he continued around the corner, certain that he could find a parking space, rush in, buy the cigarettes, and be back before the children got seriously wet.
The view of himself as a father who would "actually leave the kids in the rain while he ran after cigarretes" was humiliating, and he quit smoking.
