Yes, I would be upset too as I would like to know when I was going through these episodes.

Worse, you asked her to tell you, yet she still doesn't. If a client has awareness of what is going on, it then becomes possible to do something about it. I don't get why she is withholding this info from you.. Has she said / have you asked her *why* she won't tell you in the moment. I think this is a conversation worth having.

I would also be very upset by her saying:

It's *your* session and hence, *your* time. Even if you were to stay silent or stare at a piece of furniture for the duration of the session, she ought to respect that and not shut the session and/or the client down. Her deciding to kick clients out early is far from professional.
