Mine gave me a reading list before I scheduled, so I don't think he would likely be upset if I mentioned something from those books.

I read a ton though (I have a very carefully organized library of more than 1,000 electronic textbooks, some of which I've read through a few times already!). If I'm curious about something I read, I usually end up trying to ask in roundabout way (no formal terminology / jargon, no references, etc.). I don't trust myself to have high-level conversations in realtime, so this approach seems to work best for me.

I have slipped up once previously though (when talking to PCP, she offered to print out article from medical reference, and I accidentally told her I'd already read it). It seemed to make her nervous, so I do regret sharing that information, but there were parts of it that were nice (mostly being able to talk without a filter -- felt way more authentic!).
