Thats interesting. It sounds like your t is getting into bad introject or bad object stuff? Im not really clear on this, but it reminds me of when my t and i both use to yell at each other, "you are acting just like lunas mother!" Which would mean - now that i read what your t said - we were diminishing the other person in the same way as my mother would. And yes that gets into countertransference etc but i believe we can situate the source of that attitude in the mother - not the t or the client - we just borrow it; we imitate it; we slip into it unconsciously; its how we were formed.
