French in France intensifies speech self-monitoring. [fact]
The Negro arriving in France will react against the myth of the R-eating man from Martinique. He will become aware of it, and he will really go to war against it. He will practice not only rolling his R but embroidering it. Furtively observing the slightest reactions of others, listening to his own speech, suspicious of his own tongue–a wretchedly lazy organ–he will lock himself into his room and read aloud for hours–desperately determined to learn diction.
