I don't have a child. It's pretty boring.Nor did I make any effort to calculate them.That said, yes adoption doesn't increase population, but that doesn't preclude surrogates or other genetic options. So really, the numbers aren't calculable.
And my original comment was half-joking, too.
I have a child. Nothing makes you wonder what not having one is like than when you actually have to put up with daily drone and that chalk board angst dirge of that pubescent rusty squeak where every conversation ends in tears or a hand out of the last coins keeping my wallet from floating away.
I have a cat, though.
I was once an idiot child who had an idiot child.
That's a lovely story.
