I'm going to ignore the "one thing" part and list a few things.

- the fact that she self-discloses about her own social anxiety
- the fact that she always goes overtime with me when I am her last patient of the day (usually) and even sometimes schedules the people after me at 7:45 instead of 7:30 to give me extra time for free. I can't believe she does that for me!
- her "presence," she is always truly listening
- her honest concern for my well-being
- her genuine nature - she is always "real" with me
- her gentleness. She treats me with such care.
- her humility. It is so very endearing.
- her perfect balance of calling me out on things while also validating my feelings and who I am.

Wow, I love her (in a healthy, professional relationship way).
