名師大咖面對面，有問有大收獲多。American children's ritual of hiding lost teeth under their pillows probably derives distantly from this practice. But there is an obvious difference， for when Suzie conceals her baby milk-tooth， she fully expects it to be found， and by a good magician， not an evil one. Moreover， she expects to be paid for having surrendered it， and at the going rate. Nothing mare clearly suggests the blithe commercial gusto of our culture than this transformation of a fearful superstition into a cheery business transaction.
