That made me smile, CE - both because I imagine you (and she) are right, but because I imagine my T would not like it for the opposite reason. I would use such a recording to beat myself up about what I said that was stupid, what I failed to say, and how stupid my accent sounded. And I do believe in the observer's paradox, that when you record natural speech the act of recording renders the speech unnatural. I would feel even more awkward if my words were in fact recorded. Plus, for me the fact that speech is ephemeral isin itself important.

It would be nice to have a recording of some of the strengthening things T has said. But not worth all the drawbacks.
