Imagine the damage that had to be undone.

Our eight-year-old neighbour, Jonah, runs around our house. He has whooped our kids into a blind frenzy.

Jonah: It's Christmas Eve! Santa comes tonight! Tomorrow is Christmas!

Me: Um, it's actually the 23rd. You've still got two days until Christmas.

He stares at me. I am clearly a moron.

Jonah: (to me) Whatever. (to the kids) Whooo! Tomorrow is Christmas!
