My T moved offices earlier this year. I think I said "this is a nice place!" or something like that when we first met in the new office. Now that I read this thread I wish I had said more, because I think I was nervous that it would really change the dynamic (but it didn't or maybe made me feel closer to him since I didn't have to check in with a receptionist anymore).
It has been many months since the move and I still feel like I have barely looked around much in my T's office. I tend to just stare at the rug near the door like a weirdo the whole time, lol. Someday I will look around more!
