Yeah my idea is somewhat like a therapists approach. The patient is made to see things in a "new light", and then makes the choice of me over the therapist while under the impression that neither therapist nor I have actively made them think such a thing.
Maybe small remarks, that slowly but surely create a psychological momentum in the patient, to your favor. It's interesting because a therapist is supposedly a passive player, but with so much power. It makes me think I have to appear passive myself or the patient may doubt me.
& as to your idea, maybe you mean something like casting the negative role the therapist has given you, back to the therapist? Changing your behavior is an obvious solution too, but who the hell keeps that up permanently, you know?
