white lies

A 'little white lie' can be described as an unimportant lie (especially one told to be tactful or polite), or told to avoid hurting someone's feelings. So it is basically a lie told to add positivity to a situation rather than negativity. This applies in all cases studied including the crazy bride, James Frey and Grey Owl.
Of the three I believe Grey Owl is furthest from the label of being a liar. Having been re-born into a tribe and adopting a new identity his situation is legit. Of course he was born English and has no ounce of Native blood in his body, it is his spirit and soul which was adopted by the wilderness and he continued to live in that way, passionate about the forest and everything in it. His identity had changed drastically, claiming to be half-blood or named Grey Owl or part of a tribe is not far from the real truth at all.
James Frey on the other hand, is a little more severe. Having been investigated on his memoir, which he insists is non-fiction, and error in his story telling has been revealed. Yet we have studied that memory can be drastically changed by time, emotions, personal experience etc. The article 'A Thousand Little Lies' makes his story seem drastically false. Regardless of this I believe it is his life and how he perceived it. He could have even been writing from his own point of view, how he regarded himself at that time. Maybe he thought he deserved to go to prison, maybe he desired so strongly to rebel that he convinced himself it actually happened, or deserved to have happened? No matter the case, his novel is about his life and it has captured thousands in the pages and even changed peoples lives. A story of hope for addicts, alcoholics and criminals. A story of triumph against all odds.
The crazy bride clip on youtube doesn't apply to the category of a white lie, in my opinion. The whole film is a fake, but maybe it could be a white lie because it was made to entertain? I'm not sure how this video fits into the category or how it can be vouched for, other than the fact that it is entertainment.
In conclusion, I think white lies are absolutely acceptable in these cases. Whether you change your identity because you truly believe you are living where you belong. Or if you're writing about your own life and you twist stories or over exaggerate for the sake of a successful story. Whose place is it anyways to investigate your story and tell you you're a liar? That's just a bit rude if I say so myself.
