I feel like my T knows a lot of the types of things you mention, too. Definitely my sense of humor because that comes out in session--I'll often joke about things when I'm nervous (well, and when I'm not). And I've mentioned concerts I was going to and song lyrics, though sometimes I think about playing a song for him in session, just so he can have more of a sense of the kind of music I'm into (he's not into music and quite clueless about it), and he knows I'm a vegetarian, what sports teams I root for (and what sports I don't care/know anything about), etc. I guess for me those sorts of things just come up naturally through the course of therapy, plus we'll sometimes have small talk at the beginning or end (definitely at the end, while I'm paying him).

However, I have thought before that I'd like him to see me out in the world acting competently rather than sitting there crying. That he could see me in a good parenting moment. If he could see me at a professional event (I work from home, so that would be pretty boring for him to see!) And I've mentioned showing him photos, like of my family (think I showed him my D once), and asked if he thought that would be helpful to him, and he said no. I may still suggest that... I've mentioned my H's height (he's tall, unlike T!) and that he's of Irish heritage and a bearded redhead, but never shown a photo. Part of me wants to see a pic from my wedding day, where I looked really polished (thanks, makeup artist and hairdresser!) and happy. Or maybe just any photo where I look really happy. Hm...

ETA: In some ways, it would also be interesting for him to see my Facebook, to see how I present myself to the world in that way. (Or possibly some of my posts on here...) Or I've thought that it would be interesting if I was out to dinner with, say, my parents, and he was sitting at a nearby table, observing the interactions. Because it would be interesting to have a therapist's view of how those go.
