My favorite moment of the day was whe, while driving home, William started counting down, from the largest number he knows. He said: "infinity, googleplex, one-hundred, two, one...um...ten, nine, eight, seven," and counted down to one. I was impressed on three counts, as well as amused. A) William knows some pretty big concepts for a pre-schooler, B) he got all those in the correct order, and C) he self corrected as he realized he'd skipped a few numbers he knew. It was a beautiful moment.
