Tween?

I think of myself as an adult, a grown ass person. I go to work, I pay my bills, I even drink the occassional alcholic beverage. I am 31 years old for heavens sake!! Having said this, I would like for someone to please explain to me why I am such a freaking Tween? You might as well transpose my age and make me 13 because I am a tween. I love all of the same things tweens love. Hannah Montana - I DVR her show folks. High School the Musical I am actually considering going to see Zac Efron's new movie "17 again". MTV reality shows, last night on The Hills Audrina gave Justin-Bobby his walking boots. Twilight, lets not even go there: Read all the books, read Midnight Sun (haven't read it? Check it out), had my friend burn me the soundtrack, borrowed the movie from a friend and didn't want to give it back - I am slightly obsessed.
I think being a tween is something that is just in my DNA. When I was a true tween I was the epitomy of tween. Boy band - loved 'em. My walls were papered in every Teen Beat and BOP "poster" of New Kids On The Block imaginable. I knew more about those 5 boys that their own mothers (whether what I knew was truth or not is besides the point). Even now as an adult I've tried to sweet talk my hubby into driving all over California to go to their different concert engagements. And I get text message updates from them (don't ask, its best if you don't involve yourself)
I wonder if a study has been done to see if teenages (especially females) have a predisposition to "tween" behavior. I am a daydreamer, always have been. I wonder if that is what makes me predisposed to my acts of tweenism. Regardless of why I am, God help my husband!
