Sometimes surprised amusement, especially when I'm correct. Over the years I've deduced things about her personality that aren't very visible in her therapist persona, like that she's really stubborn and independent. Often she briefly confirms or denies my suspicions. Sometimes if I'm way off base, usually when I'm ascribing negative reactions or feelings to her that aren't there, we talk about why I might misinterpret how she is feeling. Therapy is all about me, but I don't think she minds being "known" by me when something comes up in the room. She once told me that I am "pretty frickin' perceptive," so maybe I have her pegged more often than she admits.
