A woman of twenty-eight, about three years her husband Paul's elder, Kathryn Hobbes is from a working class family and feels a little intimidated by the well-educated young people among whom she and Paul circulate. Yet Kathryn is also a down-to-earth person with a pragmatic view of life, and she regards the philosophizing of Paul's friends with some skepticism. This doubt grows in her as the novel goes on, and the many ideas of the group's members amount to very little in practical terms, even as their daily activities grow increasingly more chaotic. Nevertheless, the growing emphasis on wild parties seems to wear down Kathryn's resistance, especially since she dislikes her job at a public relations agency and hates her boss. Paul is really the only important person in her life, and she needs to be involved with him. If it takes going to parties and drinking nonstop, she's willing to do even that.
