“ I wore only black socks, because I had heard that white ones were the classic sign of the American tourist. Black ones though,- those'll fool 'em. I supposed I hoped the European locals' conversation would go something like this:PIERRE: Ha! Look at that tourist with his camera and guidebook!JACQUES: Wait, but observe his socks! They are...black!PIERRE: Zut alors! You are correct! He is one of us! What a fool I am! Let us go speak to him in English and invite him to lunch! ”
