I got some bad medical news, which I shared with my t when it happened. About 2 weeks later, she asked how the follow up went and I told her I didn't want to talk about it. So we didn't. That was the only time something like that ever came up. My t has an amazing memory, so I know she remembers everything but (except for the above instance) she never brings things up from prior sessions. She lets me decide what is important for that evening.
