There’s this line

in J.M. Coetzee’s Disgrace, where the protagonist (dirty old scholar that he is) imagines the escort he frequents making fun of him. He believes himself wise, saying “He has a shrewd idea of how prostitutes speak among themselves about the men who frequent them, the older men in particular. They tell stories, they laugh, but they shudder, too, as one shudders at a cockroach in a washbasin in the middle of the night. Soon, daintily, maliciously, he will be shuddered over. It is a fate he cannot escape.”
