Of course you did nothing wrong! If your T didn't want her clients to see her art, she would not have "advertised" it at the office! I probably would have done the same thing. When I was researching my T before I started seeing her, I noticed she published a book. So I bought it. I didn't finish it until we'd already started therapy, but I did tell her how I found out she had a book, that I bought it, and read it. I was trying to find reviews/etc on my T before I started seeing her....unfortunately I didn't find any, but when I searched her name, her book came up several times. I actually really liked it, it is a memoir of her childhood. At first I wasn't sure if I should admit to her that I knew about it and read it, but when I told her how I found out it was out there, she completely understood, saying I SHOULD do research before seeing someone.
