I am guessing she does think of me along with her other clients.
I think of my students beyond my normal day and figure out ways to help them to grow, so I'll bet it is the same for my t. I am also betting that these are just passing thoughts because she needs to focus on her family first outside of work.
My sister-in-law used to work for a group of therapists and she said that the conversation of clients came up quite often outside of work, especially when they all headed to happy hour. Like any "job" they found it helpful to discuss clients with each other in order to process and wind down.
