When my T redecorated his office (substantially), he sent me photos of it before my session, so I could see it and get a little bit used to it before setting foot in it. He also allowed me to give him a gift, a decorative item that went well with his updated office. He also sent me photos of the old space (because I had neglected to take any). All of those things helped immensely, but it was still a hard transition. I couldn't even sit in his new chairs for a few sessions. I just sat on the floor with my back against the wall, looking at them. (So weird how important the space itself, and the things in it, become.) He was very patient and understanding.
