Dear T,
Thanks for the warm handshake and holiday wishes at the end of session today. This sounds so silly, but it was nice that you stood up for it this time. It feels like I've known you for much longer than a little over 3 months. I think you're a good T for me. You both accept and challenge me. And that's what I need right now. I hope you and your family have a wonderful holiday.
See you next week (glad you're seeing clients Wed.-Fri.!),
