" Do you think Americans are just too open and outgoing for their own good? Do Europeans still make fun of Americans on this count?' David asked.
Foucault replied, 'Yes, I have heard Europeans scoff at American friendliness, the American way of 'being nice', but they are mistaken. We spend a lot of time with strangers, so why not enjoy it? We probably spend at least three-fourths of our time in very short encounters with people, in chance encounters. This way of relating to people, then, is very important. Why buy hostility with your groceries? Be friendly with the checker and the stock clerk! Antagonism against each other only saps the energy that could and should be directed against the systems of power that oppress us. "
