Blithe, wanton and insouciant, Sylvia Wright talks back. At the sexual anthropologists who say America is a woman's world. At those fatuous articles by the once obese-now-slender. At lush magazine articles which presume a fully stocked larder every day of the week and a refrigerator devoid of left-overs. Her salty and astringent observations on Life's little lunacies and her reactions to them will encroach on that circle who second the motions of Dorothy Parker and Phyllis McGinley -- although her comments are neither as barbed as the former's nor as airborne as the latter's.
