This is really interesting to consider.
I think he would say he is proud of me, especially when I stand up for my own values and hold to my integrity. And that he has seen me grow a lot over the last two years, and that he enjoys working with me and he cares.
All these things he's said to me before, and I think they are at the core of his feelings towards me.
And...I am absolutely going to ask him to consider this and write it down for me!
