I saw my T for two different periods of 9 years, 9 years apart from one another and it was definitely much easier and more likely to talk about "us" in the second period, often through remembering what things had been like before, etc. I found that a good way to open discussion, telling her things that I couldn't tell her at first, back a few years earlier, what I had felt and thought, etc. It was very interesting because we'd get talking about our individual perceptions of a particular office, for example, and I was always surprised at her responses. Eventually it got so I could talk about things "sooner", like when we had to use the Director's office instead of the one we usually used (and it was much nicer) and comparing the two offices and the orientation of the chairs and how the chairs seemed bigger or more/less comfortable. Often my wrong perceptions would come out, I would say I was glad she had X in the other room (foot rest, say) and she would be surprised because she did have X it had always been there, that kind of thing.
