My situation is perfect for me. There is a clock on the wall right behind T and I can monitor carefully my session. I know what I want to talk about and I decide if I want to stay on topic or switch to another topic depending on the time frame. But I can do all of that because I'm very aware of the time. I like that. I would hate not knowing where we are time-wise in a session. It would be too hard for me to not know how much time I have to complete my thoughts. Also, I would hate having my T tell me it's time to quit. I like being in control of the ending. So, I am the one who begins the winding down and when it's that moment to quit, I get up and leave. Very easy, very painless.
