    On the 12th I believe it is when I went in for getting some tattoos under some big radiation device that they're going to be using for radiating that cancer tumor and the person that they went through that with me was very helpful and talked me through it, almost constantly made me feel very comfortable. So if that's who were talking about, he... he... I would say he was great at his job. Couldn't be better.
