Claire has made her decision.

I'm sure it's been around for a few weeks, but today was the first chance I had to really test it.

I gave her a pencil, and put it in her left hand. She made a few scribbles, then switched to her right hand, smiled, and started to "write."

So two left-handed parents have produced two right-handed daughters. I'm a little disappointed about this, I think. But it's her brain telling her what to do, and it's hard to argue with genetics.
