Well, we did it - we went and showed her. After a lot of encouragement from me that one of us got to sit on the floor and show the T her stuff.
It was a good way to share our system (part of it, at least) with the new T. She asked questions about each one, and we were able to move the objects around to show how relationships, awareness, and outside functioning has changed over time. We worked with the objects for most of the hour.
Hard to know what the T thought of it. After taking notes on the different alters in the front group she asked questions like "Who is the most sensible?"... "Who is out most at home / while driving / at work / while shopping (etc)"... "Who has the most fun?"... "Who is the most emotional"... etc etc. We don't like giving out names in general so once we had told her who each object represented we were able to answer just by pointing or regrouping the objects. And when we switched and she noticed she asked who was out and we could just point to the object instead of saying names, which we really just don't do.
Kinda feel like we have to take them every week now. Glad we mustered up the courage to share it with her. Will have to wait and see now what the fall out is from sharing so much.
