“[T]he children themselves repaid her griefs with small joys. These joys were so small that they could not be seen, like gold in the sand, and in her bad moments she saw only griefs, only sand; but there were also good moments, when she saw only joys, only gold.”

—Leo Tolstoy, Anna Karenina, 1877, translated by Richar Pevear and Larissa Volokhonsky, 2000.
