Hmm. After answering I read some more answers. I wonder if part of the reason I don't find any of my therapist's interventions pointless is that I have had the same training as him in the same schools and always know where he's going with it (if I'm in the mood to wonder). So even if he just mirrors what I tell him or says something about himself or makes a clumsy joke, I know what benefit it might have therapeutically. So maybe that also contributes to my feeling it all has a point.
