A psychiatrist is writing about teenagers, with daughters of his own constantly underfoot. The 17-year-old has a menagerie that includes a Greenwich Village beatnik and a Peace Corps reject. He discovers that the girl has married in another state under an assumed name. The trouble is, she won't say who her husband is, leading the harried father to some sleepless nights. The younger daughter is reading "Fanny Hill" and concludes that it is tamer than her own household.
