I wonder if, instead of deciding now what you will do the next time your T goes on a break, you could discuss this with her the next time you see her. Since this was not her normal behaviour before a break, it seems like a good idea to let her know that it wasn't helpful for you. (As we all know, there is no uniform way that Ts think or act, and the good ones are actually flexible and will change their behaviour based on what the clients need.)
