The therapist asks: Are you suicidal? The patient thinks: What does he want me to say?
The therapist says: I suppose you're a little suicidal. The patient responds: Well, now and then.
One of the basic rules of psychotherapy is never to ask a question when you can make a statement. People respond to questions by being defensive; statements catch them off guard, and, depending on how they react, the interviewer gets a more accurate sense of what the patient really thinks.
This idea - avoiding questions in an interview - was a basic concept taught by Leston Havens, an existential psychoanalyst, in his classic paper, "Soundings."
