I have had the urge to leave a few times, and said so to T. Once, T's next client came half an hour early(!) and tried to get in - T's office door is locked if you try it from the outside so he couldn't actually get in. T went outside and told him to come back at his scheduled time. I panicked rather seriously and told T I thought I might have to leave. Other people coming into the therapy room is a frequent nightmare for me, as T also knew. It was partly the fact that T was visibly angry at that other client that helped ground me enough to stay. I got the impression that it was not a regular client.

So no, I never actually left an appointment early. I know T would not come after me if I did. That is, I assume he wouldn't.
