I just spoke to Leo on the phone - I just got to Boulder and he's still in Honolulu. He was out at the sushi bar, eating oyster shooters. He said, "Mommy, I have a question for you. Why does Sid the Science Kid have a microphone? None of the other kids have microphones. And they are small kids. Why is he the only one with a microphone?" All in his southern drawl - it comes out real slow.
Sid the Science Kid is a TV show on PBS that we never watch because we don't have a TV. But Leo has learned to turn on the Mac, turn on Firefox, type in PBSkids.org, and watch Sid the Science Kid videos and play games.
I asked him if he uses the microphone to talk. He said, "Yes, it comes in handy."
