Some T's are just amazingly insightful and excellent at picking up on the little clues we give them. There've been a few times where my T has come out with something about me, and my first impulse is to deny it, even if it's true. I very rarely speak before considering my words, so I often stop myself before I can deny it...but then I usually respond with "yes, damn it, that's correct Why do you have to be so insightful! I was happy over here in denial land!"

It's not too late to tell your T that she was right, if you think it's something you need to explore. In the next session, just tell here that you were shocked and struggling to admit she was right, but she was.
