No. 1 forgot a few important things: a spouse's illness and some details of a very traumatic event. I didn't bring it up, but wish I had. If you do bring it up, I would make it firm - be polite but state definitively that you DID talk about this.

Nos. 2 and 3 remember everything so far, but they also take very detailed notes, more detailed than No. 1, who writes keywords haphazardly on a piece of paper.

Everybody forgets things but these are major details that are important to your mental health.
