Dr. Balis had quite a bit of loathing for Joseph Mazukra as seen in this session's notes. Dr. B even told Joe that it is his own fault his life is a mess. During the notes on that session, Dr. B. admits that he almost lost his cool.
It takes a lot to rattle Dr. Balis, but it can be done. As screwed up as Joe was, I don't think Dr. B ever cussed. Muy interesante!
