Being the youngest kid in my family and usually the youngest of my circle of friends, I always wanted to be older. I loved having a birthday because it was cool to be a year older. Now, after all these years I'm finally over it. (It only took decades.) So I'm done with it. I'm officially not counting the years anymore.
Why count anyway? Because I'm really many ages -- parts of me are still super young and naive and other parts of me, due to lots of life experiences, are way, way older and smarter. So this day, my birthday, is now about reflection -- and satisfaction -- because I'm still me, not a number, after all these years.
