In the era that they pulled off the school thing, yep, I believe that they could have pulled it off. I ditched school every chance I got, in that era. Some of my creativity would not fly today, but, it got me out of school back in the day!
I don't buy the shower story after the 20/20 interview. In that interview, the initial shower story changed, significantly. I'm not sure I buy much of anything that sister is selling, at this point.
I gave up on what the sister says days ago. I gave up on the brother tonight when he said they had all those children because they were hoping for a reality TV show. I don't think he knows what a reality TV show is if he thinks they wanted cameras around all day filming how they lived their lives. And then there are these former neighbors. The one man claimed when he got off work at 1:30am, he saw the children marching from room to room. That I might believe, but when asked how long they were doing that, he replied "For hours---all night". So he finished working a night shift, came home late at night, and stayed up for hours watching the children marching? Um no. He watched them for a few minutes and went to bed to go to sleep IMO. And then we have the woman who, when she was a child, used to go over to play with the children when they lived in Texas. She said there came a time when she went over there to ask if she could play with the children and no one would answer the door anymore. She goes on to say when she looked through the window, a baby was in the playpen. That I would believe too. But she goes on to say the baby was always in the playpen---day and night--and was never taken out. She must have stood there all day and all night, looking through the window, to know that.
The only person I believe so far is the Elvis guy.
