The lack of more thoughtful reflection and considering her role in all this, bringing up textbook interpretations quickly ("critical parent"...) to explain your reactions, talking over you. My impression might be because of the way the story was presented though, perhaps in reality it was much more nuanced. But I personally just don't like anyone much who does not openly consider their role in a conflict or just keeps bringing up explanations that only or mostly concern the other person or one possible view, therapist or anyone. Again, lack of open reflection. I think there are always at least two people involved in every interaction and how the approaches, personalities etc of the two interact can sometimes be the most informative and realistic IMO. I know that some people would say that's not how psychoanalysis is supposed to be done and perhaps that is true, but it does not change my opinion it. If anything, I think the therapy is supposed to probe into client's defenses primarily but it's a reaction to something and if the original something is considered only in a one-sided manner, the interpretation and conclusion can be very misleading sometimes. I don't think many Ts are intentionally manipulative for the sake of it, it can more often be the side effect of not being able to think outside of the box and not willing to address own short-sightedness, trying to mold (manipulate) the "reality" (client) into an easier, more established view. All this might just be my own preference though regarding how I like to interact, definitely not something applicable to everyone. I know that I tend to clash in views with a few people on this forum, for example, so there is that. What I see as manipulative may mean something completely different to someone else. But I am usually turned off by recurring, stubborn defensiveness and lack of an open mind to consider alternatives.
