I think I would use it to discuss the therapeutic relationship. And the "therapeutic bond." I know how my T views it, and I'm curious how other T's do. What do they consider a good client/T relationship? What would a perfect relationship look like? It would be interesting to get another point of view and compare it to how things are going now.

I think the suggestion to discuss where you're at overall right now would be good, just to kind of review and get another perspective.
Also, if there is anything specific you've wanted to ask your current T but didn't feel comfortable doing it, this would be a good chance to ask someone else.
