The innocence of a 6 year old

Last night Mary Jo was in her room. I peeked in and she was on her bed, listening to the Jonas Brothers on the stereo and reading one of those teen magazines that had the Jonas Brothers in it. So I watched through the crack of the door for a bit thinking about how my baby was growing up. And then she started kissing the pictures of the Jonas Brothers in the magazine. It made me laugh. I remember doing to same thing with pictures of Michael Jackson and the guy who played Bo Duke in the Dukes of Hazard.
A few minutes later she came out to talk to me.

"Mommy, I wish I was the Jonas Brothers dog"
"Their dog? Why their dog? Don't you wish you were their girlfriend?"
"Eeew NO!! I just wish I was their dog!"
"Well why would you want to be their dog?"
"Because they love their dog and take it everywhere"
"So you wish you were their dog so you could go everywhere with them?"
"Yep"
"Well why not be their friend and then you can do fun stuff with them too and go to their concerts and stuff"
"No, cause they love their dog best. You know what? There was picture of the Jonas Brothers kissing their dog"
"So you want to be their dog so the Jonas Brothers will kiss you?"
"Yeah!!"

So maybe she's not so grown up just yet.
I'm trying to make sense of how being a dog that they kiss gets a "YEAH!" but being their girlfriend gets an "EWWW!"
