I've seen other clients before and I do feel a bit jealouse. Most occasions I don't see anyone in the hall and T's office door is open and I just walk in. It's like I'm her only client

Other times when I have seen other clients I check them out to see how I compare. A bit childish I know. :-) One client I recognized but never said anything to and I don't think she saw me.
I prefer to see the client before me than the one after me. My T doesn't address the person after me who's sitting in the hall until I leave the hallway which I think is nice :-)
