A conversation with Sister last night, after we returned from the library with a book on puberty for her:
Sister: Mom, I think Lily and I have had the wrong idea about sex.
Me: Oh really? In what way?
Sister: Well, we thought that every time you had sex you got pregnant. But in this book it says there are other reasons why people have sex.
Me: (weakly) Oh, uh, you thought that, huh? Well, no, a woman doesn't get pregnant every time, but it can definitely happen.
Secretly I was thinking, "Rats! They're on to us!" But I promise I didn't perpetrate this little fiction on Sister on purpose, like, strategically.
She has been utterly engrossed in this book for nearly all her waking hours since yesterday, though I forbade her from taking it to school on the pretext that it was a library book I didn't want lost. The truth is that I have no idea what sort of thing might happen on the playground as a result. I could easily imagine Sister holding forth on all sorts of titillating topics to an astonished 9- to 10-year old crowd. When did I first become aware of the facts about sex and puberty and that sort of thing? I can't remember at all...
Her friend Lily got her first training bras yesterday and they're having a sleepover tonight at Sister's grandma's house. Oh to be a fly on the wall over there tonight!
