What you T's office looks like? What do you like or not like about it?
If this has been done before, sorry. I just thought it's be a lighter note. Here's what mine is like.

Small office, he runs it himself. Rents space in an insurance company's building.
Lots of books on two bookcases. Most books are about the brain in some way or other. There's a white teddy bear on the top shelf of one that he bought for me to use during sessions.
One loveseat (where I usually sit) and two wingback chairs across from the sofa.
His desk in the corner. The room is lit by lamps, no overhead light. Two small fountains making white noise on a side table behind the chairs. Two large fake plants. Windchimes moved by a fan. Lots of "soothing" type sound. It actually irritates me so he turns it off. LOL.
I think he overdecorated a bit, but it's nice overall.
