Yeah, my T has a pretty good memory as well - he's forgotten important things I've told thim, a couple of times, but most of the time he keeps very good track of what I tell him. He sometimes reminds me of things I've forgotten, even. But I know that he devotes a lot of time to going through his notes every week. He puts in at least two hours' work, including reading up on new research related to our work, for every hour I'm there... and he does the inbetween work even when I have to cancel (which is one reason why I don't find it unreasonable that I have to pay for cancelled sessions.)
