I had the next person just walk in to the office one time while I was still there. It was odd to me that she would just walk in to the closed office of anyone let alone a therapist and without even knocking first. I simply assumed that next client has a much different interaction with the therapist than I do.

I saw a therapist once who was in an apartment with several other therapists who had turned the various rooms into offices. I hated the waiting room with other people because I dislike having anyone else see that I am there to see a therapist and it seemed too much a breach of privacy to see the other clients too.
