My T doesn't have a waiting room. I usually ring the doorbell (once) at my allocated time. If there is nobody else there, he lets me in pretty much straight away, but if there's another client, I wait for them to come out. I noticed that a lot of his clients are middle-aged men dressed either in suits (I guess they come straight from work) or in smart-casual attire. I also saw a few elderly gentlemen coming out (or waiting when I came out of my session). Sometimes, if there is a new client after me, they tend to ring the bell earlier than their allocated time as they assume he must have a waiting room. A few months ago, a youngish guy did this and T had to go down and explain that he was still in the middle of a session. I saw him when I came out and he seemed apologetic and a little embarrassed.

Once I saw a young woman which made me super jealous because, in my head, I am his only young female client (probably not true). She smiled at me and was super nice, held the door etc. I felt bad for my jealousy and I really wondered what sort of problem she was there for. I saw her once more after that, and I think that must have been her last session because it was almost two years ago and I haven't seen her since.

I also noticed a few teenage boys that go see him. One of them always greeted me and complimented me on what I wore, which I found funny and sweet in an "I could be your teacher" sort of way. There were also a couple of families who were clearly there for their kid. One family thought I was the receptionist greeting them when I came out of my session, which I found quite awkward. Had to explain I was a client and that there wasn't a receptionist/waiting room.

it's interesting seeing some of his other clients and it makes me wonder who they are./what they do/why they are there etc.
