In Vladimir Nabokov's "Laughter in the Dark," a man experiences a curious twist of fate when he loses a diamond cuff-link in the ocean. Two decades later, on the same day, he enjoys a large fish meal, only to find that it does not contain the diamond. This event highlights the peculiar nature of coincidences, where events align in unexpected ways.

Nabokov's observation emphasizes the randomness of life and the whimsical aspect of chance occurrences. The story illustrates how time can intertwine disparate moments, yet sometimes we are left without resolution, as the diamond remains lost in the depths of the sea.
