In Richard Philcox's translation of Frantz Fanon's Black Skin, White Masks, he includes the following sentence:
I try to read admiration in the eyes of the other, and if, as luck would have it, the other sends back an unpleasant reflection, I run the mirror down: the other is a real idiot. (Italics mine)
What does to "run the mirror down" mean? I've never heard this phrase before. Is it an unfortunate translation of a French idiom?
I assume that the "run" in this case is used in the sense of running a flag up or down a flagpole, but then why is he running the mirror down? Isn't he bringing the mirror to bear, i.e. running it up the flagpole of his body?
