the be-nice-to-strangers is beyond me. how can she paste that smile on her face for so long while checking so many people out, and greet everyone with the same pleasantness. and then make small talk, "enjoying the sunshine? i'm loving every minute of it". how can she love the sunshine when she is indoors the entire day beeping objects and cards and smiling and saying, "thank you, have a great day". i guess its nice to be nice and to have people being nice to you. but did anyone wonder about the dipping curve of the marginal utility of niceness.
