This evening, just as I was tucking the kids into bed, a thunderstorm was rolling in.
I was in Simon's room, closing the window and the curtains, then I went to kiss him goodnight. After the smooch, he urgently held up a hand to detain me.
Simon: "MAMA! WaitWaitWAIT! There's a special kind of CAKE! You can only make it when it's storming. It's called "ThunderCake!" You should make that. Now."
