I think it's pretty common and reasonable for therapists to take note of clients' positive characteristics when relevant, and many of those characteristics are more highly prized if/when they're rare.

Personally, my therapist tends to more often note the ways my experiences and perspectives have been rare or unusual from a neutral or negative perspective.

He has used "brave" once recently, which I rolled my eyes at at the time but which in a less negative light I think he was correct about.
