Well, I think all T's use interventions therapeutically, like saying things intended to bring out an aspect of our personality or emotion such as anger. I have definitely wondered from time to time about things T has said.
But, the alarm clock? I would flat out say to T, "what the hell is that?" LOL
I'm unclear about the "I know that he knows that I know" thing that's going on between you. Can't you just bring it to light? Why carry on in the dark?
I would definitely ask T if I was wondering.
