I have some rules with my T. They're more about words she's not allowed to say. We also have an understanding that if I say "Can we not talk about this anymore?" or something similar, then she stops the conversation immediately. She is expected to tell me if there's ever a time that I won't be able to contact her (i.e. she won't have cell service). A lot of things that might be "rules", like cell phone on silent when in session, she already does. My T is respectful of my time with her.
