On the surface of things, the whole idea sounds pretty ludicrous: a therapist supervising him-or herself is sort of like trying to see the back of your own head-without a mirror. Even if a reflective object was available, the whole enterprise is so awkward, the angles so limited, the view so restricted, that it hardly seems worth the effort…unless, of course, there is nobody else available who can tell you that there is some unflattering indentation.
