So. This morning, before anyone else was moving around, Micah meandered into the kitchen with his water balloon, to where I was making the breakfast waffles. He was quite proud of that balloon, as it was the first balloon he'd ever been able to tie off himself.

We got chatting, and somehow we got onto the problem of pregnancy. I can't remember how it came about, but all of a sudden he was saying, "Well, So-and-So couldn't have a baby". To which I replied, that, well, as soon as a girl starts having her period, she could, technically have a baby.

So, he says, what's a period?

Ah.

I was, momentarily, stumped, but then I reasoned he's 10- well, really, only about three weeks shy of 11. Why shouldn't he know what a period is?

So, I told him.

I drew diagrams in the air with my hands, and told him of the wonders of the female gynecology. How the uterus is made to be like a nest for the baby to grow in. How the Father has the seeds in his testicles, and the Mother has the eggs in her ovaries. How the Father's seeds come through his penis inside the Mother, and when they meet an egg a baby can be made. How every month the uterus gets ready for making a baby and if a baby isn't conceived the uterus sheds it's protective lining, which is made up of blood and tissues to feed the baby, and then the whole process starts again.

Yup. I told him.

So, he says, What would happen to the marble inside this water balloon if I put it in the freezer?
