Being a Grown-up

Today I realized that when my birthday comes I will closer to 30 then 20. Yuck! And I keep wondering if that is when I'll start feeling like a grown-up? Is there an official day you feel like an adult or does it just kind of creep up on you? As of right now I still feel like that akward 11 year old girl who is old enough to wear a bra but her mom still puts her in lacy socks. Do we ever get past those moments or do they stick with us forever? I went to a birthday party for my friend from high-school's son. We actually weren't that close in high school, became friends kinda during senior year, but have talked more since we are some of the few our age who have kids. Anyways, I had a blast there but in the back of my mind I still wonder if I looked like a dork, or maybe the crazy girl with 4 kids, or if I just look like that akward 5th grader again. I just want to know if I'm ever gonna stop caring about the popularity thing? I mean I've given birth 4 times, bought and sold a house, bought cars, graduated, college, worked as a nurse for a few years, currently working on starting a business with my husband, and still don't feel like what I expect a grown-up should feel like. Maybe I never will.
