thirties, flirty, and fun

I remember when I first saw the movie 13 going on 30, when Jennifer Gardner's character couldn't wait to turn 30, where her life would obviously be fabulous, and at a very low point of her 13th birthday she ran into her closet and wished herself to be thirty, chanting the words "30, flirty, and fun! 30, flirty, and fun."
Why did she pick 30? I wondered. Was it just because it rhymed with the word 'flirty'?
That movie came out 6 years ago. I was 28, and I wasn't excited to be in my thirties.
Now I'm four years into them, and during a conversation with some friends over brunch the other morning, we all agreed that we were so happy when our thirties came around, so happy our roaring twenties were over.
There's been a shift in my home, I don't know if the kids realize it's happened. I don't know if my husband can put his thumb on it. I don't know if I can chalk it up to being in my thirties or being done with my child birthing stage.
Maybe it's everything all at once.
It's weird because we are still not financially stable, my husband is still in the process of changing career's. There are many unknowns.
Also where I thought at this time in my life I would have 2 full time public school students which meant more ME time, instead I find myself homeschooling my oldest son. After a rough couple of months (and that's putting it lightly) we've hit our stride and I can honestly say that it is one of the most rewarding decisions I've ever made.
There is a certain peace I feel inside, a comfortableness in my skin, a calmness about things that would have once driven me crazy.
I would chalk it up to being a late bloomer but as I said before, most women have concurred with me on the subject.
There's just something strange and wonderful about this time in my life, and I'm trying to enjoy every day of it.
