Hi Stormyclouds and welcome to PC. This has happened to me before and being quite a forthright sort of person, I made my irritation plain and upfront (politely enough) and my T was fine with that.

It probably isn't a factor of 'low priority' or anything like that, T's have their own idiosyncrasies like the rest of us and for all I know, he may have just forgotten his notes, overlooked them as his mind was focused on another part of your therapy... or was just having a scatty day

If something bothers you, it's probably best to say something there and then rather than let it fester though
