My T keeps notes she writes in during session. I have asked her what she was writing when she was writing and she has shown me. I've only done this a couple of times because I was curious as to what I said prompted something to be written. She also 'translates' them onto charts for insurance billing purposes, way more generic/cold. If I asked for her 'notes' I would be given the ones that were officially charted not her personal in session notes.
