I agree. I have sometimes had discussions with my therapist about TV shows, movies, and even Brexit because I was so mad about it. I have learned that we have a lot in common. She sometimes shares little things with me about her own life if it is relevant to the conversation we're having, which I also appreciate. I also know we grew up in similar families, so she can relate to the things I talk about. I've never actually had to ask her any questions, it just comes out naturally in conversation, which I guess is what happens when the therapist is not a blank slate. She is quite reserved (and compared to my uni therapist I think everyone is, lol), but she is not blank.
