I have no idea Probably varies depending on many factors, e.g. is it a new client, what goes on in the process momentarily, what they are specifically interested in, how interactions with the client affect them, what else goes on in their lives, and a lot more. I definitely never assumed that my T's did not think about me between sessions (their reactions also showed clearly that they did and they also explicitly said it sometimes) but also did not imagine I would be on their minds as much as the other way around.
