One more than the other is a bit more revealing. I think the " blank slate " is maybe getting out of date and does set the client up to idealise or feel ashamed. And it makes me more inclined to say things. I remember one session where my T kept dropping things - we just laughed and I said " Oh , I had one of those dropping everything days the other day ! " Like we all do. But he aimed to be human , not God , so he couldn't fail. I think he understands me very well as he's been through similar.
