"The gesticulations and facial expressions with which an American will supplement his English are as distinctively American as those of a Frenchman are distinctively French. One can tell the nationality of a stranger by his gestures as readily as by his language. In a vague, general way I had become aware of this before, probably from contact with some American-born Jews whose gesticulations, when they spoke Yiddish, impressed me as utterly un-Yiddish. And so I studied Bender's gestures almost as closely as I did his words."
