Henrietta is up at the crack of dawn every morning, cleaning up the house, taking care of the various animals, or engaging in some kind of productive manner or another. Every school teacher she's ever had has emphasized how responsible and intensely focused she is. Her new endeavor is raising chickens-- her and I are working on a business ledger spreadsheet on her PC, so she can track the expenses and revenue.
Where Henrietta is practical and grounded, Duncan is the imaginative genius. At two he was making adult-quality levels in Super Mario Maker. At three he started reading. On the verge of his fourth birthday, he constructed the entire solar system-- all of the planets, the major moons, and even the asteroid belt-- in Minecraft, with adult-level mouse and keyboard plus dual analog coordination.
I could see the two of them coordinating on major projects in the next couple of years, with Henrietta's budding interest in business and economics-- her and I have read Peter Schiff's "How an Economy Grows and Why It Crashes" multiple times-- and Duncan's pie-in-the-sky creative and raw cognitive capacity.
