Well, the Bush girls aren't saints, but they're not the reckless dingbats some like to paint them as, either. As to church, I've seen pictures of them over the years attending services with their parents. I'm not saying they attend weekly but you made a comment that you weren't sure if they EVER went to church as if they'd never stepped foot in one.
As to deciding what they want to do, Jenna is going to teach and Barbara is going to work in Africa, neither categorizes as "party girl" or "glamorous.
I certainly don't think they are dingbats but they went to public school here with my kids and I do know who they are.
