When she was eleven, Margaret Bilotti, stage-struck elder daughter of a Manhattan construction worker, collaborated with another East Side youngster in writing a play, the proceeds to buy Christmas toys for underprivileged children (gross take from ticket sale: "over $2").

Eventually a neighborhood hospital referred the Bilottis to one of the few places in Manhattan that specialize in treating conditions like Margie's, the Hospital for Special Surgery.
