I have not found anything that bothers my current t, but I have only been setting her for 6 weeks.
Previous t was made uncomfortable by some stuff I would not expect from her, as she was working in an assault crisis center, but she did leave because of burn out, so maybe that's why. She also had lots of toys and games in her office. I kinda miss it. Made the place feel safe. New t shares rotating offices (read closets) with other interns, so there's nothing of hers there that she does not being in for the session. It's kinda weird. And we are not always in the same room, so that throws me of a bit.
