Everyone has their milestones that they believe make them an "adult."
Years ago, my family went on a vacation where we rented a beachfront home. In the kitchen, they had a beautiful cake plate (prettier than this one, and pink). I wanted one. But there was no room for a cake plate in my dorm room (and no need for one.) I knew I'd be an "adult" when I had a cake plate. And space for one in my tiny kitchen.
I'm now a real lawyer. I passed the bar. But I'm still not an adult. No cake plate.
Today, though, I realized that although I may not be an adult, I am "old." How do I know? I'm too old to audition for The Real World.
Not that I wanted to. But that's not the point.
