I wouldn't feel bad about it; I think she just wanted to make sure she brought it to your attention; it's a very good piece of information!

I often experienced my T as doing that; saying something significant just as I was leaving! You could have thought of her response like that but instead you're castigating yourself :-) You say you've done it before, why hasn't she mentioned it before?

I think though that it's neither thing; neither us holding on and unconsciously doing it or one's T trying to give us something to work with between times but a more "normal"/continuous thing. I don't think there's any difference between the last 5 minutes of session and any other 5 minutes in your week; it's all your life and deserves respect/paying attention to. Behavior can't change until it is noticed. I had a hard time learning that and getting use to the long period between doing something "wrong" and catching it that gradually gets shorter and shorter until, hopefully, you catch it before you do it :-) I still remember learning to notice when there would be either my bombs or my T's bombs right as we were winding up and dealing with mine so they didn't explode at some other time in my week or responding to T's as I was walking out the door so she'd know and I knew it was important to me. And that's the whole point of therapy I think, recognizing when something important to you is taking place.
