Perhaps I did not understand the boundaries issue, but it was raised and has been raised in other ways very often in discussions here, enough to be taken up as a general concern that people seem to overlappingly share, though people may differ on what the terms really are and what is appropriate.

I didn't mean to suggest that this therapist is normative at all. In fact, sorta the opposite. That I found it curious and interesting that such an experienced therapist would say something like what he said, that it takes sometimes a push against you (and your boundaries) to really understand who you are as a therapist. That just seemed cool. And it also seemed to suggest that at least some people don't just automatically judge behavior or speech as bad or out of the limits or whatever, and instead take it in to consider how it can help them challenge themselves. That is where I saw insight, promise, and even relief. For so many who struggle with self-doubts and worries about their connections to their therapists, it just seemed to suggest that there are people who think about this even late into their careers and remain open to challenge. It just seemed to be a hopeful perspective to share.
