I think you are right that "technically speaking" Vincent seemed to do little to help himself. Lisa is also apparently oblivious to psychological help that would be available from health proffesionals. Still, with artistic license we could stretch our imaginations a bit and tell ourselves that these things are going on in the background and we only see his problems without much apparent attempt to correct them. When considering the bottom line, that he is damaged goods, and how this is manifested in the radio program is where my appreciation for the story comes alive. I am glad you enjoyed it.....Until Next Time.
p.s.- I believe we are supposed to submit our reviews before reading any others as a way to present the views without influence.
