Wrybread: "San Franciscan faces definitely tend toward smiling. In New York I think they tend toward glum stressed hurt and aggressive tensed frowns. People here want to smile, and they want you to smile, and if you don't they'll more or less ignore you. And there seems to be some concern for the quality of the smile -- vacuous fake smiles aren't nearly enough, a good smile should reflect a good hearty inner life."
