When my t was still local, she'd come out to get me from the waiting room and we'd share the polite "how are you's" on the walk down the hallway to her then-office. Once she'd closed the door and we'd sat down then she'd always wait for me to speak first, looking at me of course. I'd almost always just say "hi" and wave LOL then tell her what I wanted to talk about. She'd always end the sessions by saying something like "we've still got a few minutes, if you have any other thoughts" or something along those lines just to gently remind me of the time. Then I'd wind up whatever we were talking about, put her money on the little table between us as I was getting up, and she'd walk me out the 'secret door'. (I always loved that she called it that. It was a door from her office to the parking lot so you didn't have to go out through the waiting room.)
Now that she's a few states north of me and we do phone sessions, I call her and we still start the same with the "how are you's" then she'll say "So, I got your dreams email..." or whatever I've emailed her that I wanted to work on and off we go. The time boundary is a little different on phone sessions. There's no annoying t clock staring me in the face so I don't notice the time at all. I call her from my home office, and there's no clock in there. I don't TRY to take advantage of that fact, but I have to admit to having a couple of full 60 minute sessions because SHE didn't notice. Oopsie.
