Who is Sharon Kincaid from The Moviegoer and what is their importance?

John's most recent secretary, Sharon, sets herself above the rest of John's secretaries through her behavior. Although she is far from perfect or ideal, she is still a step above his previous employees. For John, Sharon will represent unattainable love. Since they never communicate on a personal level — he is shocked to learn she knows his first name of "Jack" — John cannot find fault with her. Instead, he idealizes her for her every trait, including the less-admirable ones.
