I told my daughter that 15-year-olds, like 63-year-olds, come in lots of different shapes and sizes. We all get to the same place, even if we arrive at different times.
In a culture where someone live-tweets a birth and in the same week a 70-year-old announces to the world that she's tired of being a virgin and is looking for someone to do something about it, maybe it's time to have a national conversation about what it means to "act appropriately."
I still call myself a girl. I'm thirty years old and I have four children and one of them is going to be seven in two months and I'm only six years older than he is.
