"Oh puhleeze!"
Oh please yourself. You're the one assuming things.
"You don't need to be a psychic to understand that the man and his wife are beside themselves, perplexed as to why the sister is doing this."
Yes, that's what they've decided to air to the media. Does that make it the unvarnished truth? I'd like to think you know better.
"It says in the story that the wife asked and she didn't give an answer, other than that she had to put her family first."
It says the wife asked at least that one time (the time she had to be dragged away by the po po incidentially), it does not enlighten us to any other myraid possiblities of conversations we are not privy to.
"If the wife knew more she would have said so."
Really? Would she? You know this person so well you can say for a fact that she couldn't possibly tell the media only the portions of things that make the sister look like a raging bitch?
"It is preposterous to think these people would go to the press if they knew there was a rational explanation for the sister's refusal to help save her dying brother"
Heh heh. What a nice, friendly, pleasant world you must live in.
"She was given an opportunity to comment and declined."
She has the right to her privacy.
You're missing the point entirely. If the couple were aware of a rational (or even embarrassing to them) reason the sister is denying her help, they wouldn't go to the press. To do so, they would have to presume the "other side" would never come out. Do they have the sister tied up and gagged? Do they have control over the press? If they went public, they had to have known it was possible "enlightening" information would become public.
"You know this person so well you can say for a fact that she couldn't possibly tell the media only the portions of things that make the sister look like a raging bitch?" I know that it would be foolish to tell the media only portions of things that make the sister look like a raging bitch, knowing that media is capable of uncovering other things. The fact that they were willing to go public, knowing this, and the fact that the sister declines to refute it, speaks volumes.
Yes, she does, indeed, have the right to privacy. And if that "privacy" is more important to her that looking like "a raging bitch", then she should enjoy it. But you can't fault people for drawing conclusions based on information she chooses not to refute.
