Good luck today, Squiggle!
I really think this is something most therapists would not (and should not) be surprised about. I think they should just assume most of their clients will be curious and may do a little digging...
I do wonder if our therapists google us like we google them... do they look us up on facebook?

(funny... my therapist keeps coming up on my "suggested friends" list!!

I think because we email a lot and our emails are stored in facebook somehow... so awkward though, I wonder if I come up on her suggested friends list as well???)
And yeah, people like your husband who have never been in therapy will NOT understand. The therapist-client relationship is something you have to experience yourself on either end to ever really fully "get."
Anyway, good luck! After reading this thread I am anxious to hear how it goes today.
