People talk about nightfall, or night falling, or dusk falling, and it’s never seemed right to me. Perhaps they once meant befalling. As in night befalls. As in night happens. Perhaps they, whoever they were, thought of a falling sun. That might be it, except that that ought to give us dayfall. Day fell on Rupert the Bear. And we know, if we’ve ever read a book, that day doesn’t fall or rise. It breaks. In books, day breaks, and night falls.In life, night rises from the ground. The day hangs on for as long as it can, bright and eager, absolutely and positively the last guest to leave the party, while the ground darkens, oozing night around your ankles, swallowing for ever that dropped contact lens, making you miss that low catch in the gully on the last ball of the last over.
Hugh Laurie, The Gun Seller
day, night
