Yes, my T has admitted it once about a particular moment (he said he saw me as a granddaughter in that moment or that he felt like a grandfather to me ... which was interesting since he's not even old enough to be my father). Another time I'm quite certain he acted out his (momentarily negative) transference toward me. He saw what he did as legitimate but I didn't, nor did my close family, nor did other therapists I talked to.

I think he experiences transference with me most of the time on some level, and I with him as well. In my opinion, transference is bound to happen most of the time. However, there's a long way from experiencing it and acting on it. To me, the most important thing is being aware of the transference and using it well. I think it's unrealistic to expect there never to be any transference.
