This would make me run in the opposite direction (I'm not someone very interested in discussing fashion with others) but had an experience with my last T that was a bit similar. That T and I had many similar interests and both of us have reading as one of our favorite activities; we figured we liked many of the same topics, authors etc. So naturally, when these came up, we often got excited and would engage in passionate discussions that could be very enjoyable but not therapy for me even if we relate it to psychology. He also liked to share his own experiences as they related to mine and I loved that but sometimes it would take too much space. I had to remind him of this quite a few times and in the end just decided not to engage at all and keep the focus on what I was paying him for.
