When it comes to writing in the voice of another I can understand how a person can take on and even portray the character precisely. As an observer of a person you idolize that person and create an image that encompasses the public image of that person or group. In life we create references when it comes to women, a woman or cluster of women will come to mind. As Harrison, speaks of his mother and aunts, they are his reference cluster. It is because he knows them and has observed them he is able to characterize them in a believable fashion. The sense that he gets from them will be conveyed because he knows what is like to preceive them and how he wants the audience to receive his character.

An example would be transexuals, they convey men or women as they see them or believe they are. They take on their personas and live out their lifestories. I mean we all live out personas and embodiements of idols. As long as the proper steps are taken to take on both the inward and outward influences of the subject, a person can speak in the voice of another. So writing in the first person of another is very possible because we have created the image and idea in our mind it is just a matter of conveying it.
