Since we are talking about other blogs that inspire a post I will point to Xbox4NappyRash: The seventh sense in which he talks about developing a 7th sense - the ability to see infertile people.
I got it a little different - I See Pregnant Women....And Small Children.
When I was a small child I would go to the beach and see other small children. Others like me to play with in the sand.
Then as I got a little bit older I became interested in the basketball court near the beach and was aware of the other basketball players that where on the court.
As a got still older, I became aware of the girls in the bikini's at the beach. All of a sudden they were everywhere - and they were the only ones on the beach.
Recently, when I go to the beach I see Pregnant Women....And Small Children all over the place.
I constantly have to work hard not to step on them as they play in the surf. These young families are new to the beach. They have never been there before now - yet now they are all of the place.
You see the mom with the stroller and the new born, the Dad with the shade umbrella and the child sleeping, the twins that are dressed alike, the family with all of their kids in white shirt getting ready for the family photo at sunset.
Where did they all come from?
