T1 has gone 9 years without changing. Well, he has changed but not in horrible ways. Over the years we have renegotiated out of session contact but it has always been a negotiation and it has always been ok.

T2 has gone 5 years without changing. I am now cutting back sessions with her. She is pleased that I am able to cut back. I suspect there is part of her that doesn't like it, but she is too professional to show it.
