Today I explained to Katherine that she couldn’t have any more bananas. After she looked to the fruit bowl to confirm that they were indeed all gone, she simply said, “No walk in park. Go grocery store and buy bananas.” She has it all figured out: there is limited time before it gets dark, and we don’t have time to take a walk in the parks and buy groceries, so she’s made her priorities clear. I sometimes wonder what would happen if I handed her a fiver, opened the outer door, and sent her to buy bananas. I wouldn’t be at all surprised if she reappeared, within the hour, with bananas and change in hand.
