I recently had to tell my T during a session that I needed to use the restroom. I'd had an iced tea before...
To my surprise, she offered to let me use the one in the back, where the therapy rooms are and not the one out where the waiting room is. I felt seriously honored and laughed at myself for feeling honored about being elevated from public to semi-public lavoratory status.
It was closer, but the one off the waiting room is nicer - nicely decorated. The one in the back was utilitarian and had shelves with supplies on them.
Isn't that nice of the T's to provide a nicer restroom for 'us' than 'them'.
