I think it was his way to show you his fondness for you. I think its sweet.
However, i think its more of a work thing than a therapy thing. It doesnt seem much different than those who tackle their most difficult tasks first, etc. Plus, people who work from 9 to 5 will most likely be last.
I had a therapist who really liked working with me too, a little too much. I totally understand your leeriness, i had similar feelings. However, my therapy turned out to be a very helpful experience. (BTW-I was a last client of the day too

)
I dont know if this was the case with you, but I used to feel uncomfortable around those who were giving of me, always thinking in the back of my mind that id have to give something in return. I realized later in therapy that i had unconscious fears of this happening in therapy too.
You sound vigilant and self aware enough; intelligent and capable of protecting yourself from Kashi if he ever steered too far from his therapist role. You're not a newbie in therapy anymore.
Sorry no one seems happy to see you. I am always happy to see a post or hug from you and can see why Kashi or any therapist would enjoy working with you.
