A form of self-deception. The phrase comes from Tennessee Williams’s play A Streetcar Named Desire (1947), in which Blanche DuBois, with delusions of grandeur, has a destructive effect on her sister Stella’s marriage to Stanley Kowalski. Stanley rapes her, leading to her nervous breakdown, and commits her to a mental hospital. As the doctor leads her off, she says, “Whoever you are, I have always depended on the kindness of strangers.” The phrase “kindness of strangers” occasionally appears in other contexts, as in “With no rain for a month, my garden depends on the kindness of strangers.” Sue Miller used it in her novel The Lake Shore Limited (2010). Talking about two characters in her play, the playwright said: “Well, you are not Jay . . . a guy who’s betraying his wife. And I’m not Elena. I’m not . . . dependent upon the kindness of strangers.”
