In general, my T treats me really well so I try to reciprocate. In doing that, I end up being respectful of his boundaries.

SweetCrusader, I think it would also be interesting to look at ways clients communicate their boundaries to their therapists. That's really hard for me (with everyone, not just with my T), but I've improved since beginning therapy. Also, I think that as therapy progresses and you get to know each other really well, sometimes the boundaries relax a little (both client and T boundaries). I know that for me there are things that might seem acceptable now that weren't at the beginning.

Anyway, if you do a follow-up article, I think the "client boundaries" angle would be interesting and is less written about than the therapist boundaries.
