I tried putting myself in Lisa's shoes
(seams like I've heard a song along that same line
), and I can understand her attitude.
If people constantly hounded me with questions regarding my father, I'd probably reach a point where I said "enough." You have to realize that every move she makes or thing she does is either compared to her dad, or made to be "would her dad approve?"
Also, I remember watching Lisa on the Elvis By The Presleys program, when she recalled the last time she saw her dad alive. You could see the emotion on her face and her voice.
There's also the instance where she responded to the comments made by a few of the MM on the E True Hollywood Story "The Last Days Of Elvis." From what I saw, she was deeply offended by their comments, especially the remarks that she said "took away his dignity."
I'm not trying to defend any actions or her overall attitude, because I have seen a few occasions where she came across as a spoiled - obnoxious jerk. However, from what I (myself) have seen, the good outweighs the bad, so I try to look at the experiences she had, along with the upbringing she received. These factors are what's shaped her imo....so before you abuse, criticize or acuse, Walk A Mile In Her Shoes.
