This paper addresses how to be an available and responsive therapist to a controlling and narcissistically vulnerable young girl. It presents an overview of the treatment relationship and specific vignettes from sessions. The paper describes an impasse that posed a quandary: how to find a balance between staying in control of the treatment while being responsive to the kind of object the child needs the therapist to be—being empathic without being intrusive—and meeting her aggression without getting into a power struggle. The author discusses how asserting her subjectivity by playfully role-playing aspects of the patient, by spontaneously using humor, and by surviving her destructiveness allows the treatment to move forward. Trial and error, reflection on practice, and informed intuition contributed to the author's understanding of the child and of the transference. Various theoretical perspectives influenced the work.
