    Yeah, I thought the Dr. Liem was - is a very good doctor and he was truthful with me and he apologized, that you know the news I had was more on the on the bad side than the good side, but that was not his fault - he just told me the truth and he apologized a couple of times, and I appreciate that, and I think he's very good doctor.
