Bennett popped his head in the room, as I was doing math homework with Nat.
"Dad," he asked. "Do cows make milk?"
"Yes, they do."
"Does milk come from cows, or do we turn cows into milk?"
"Go away Bennett!" shouted Natalie.
"Be nice," I tut-tutted Natalie.
Turning to Bennett, I said, "Cows make milk from their udders."
"Oh," he said, clearly disappointed.
"But we do turn cows into hamburger."
"That's awesome," he chuckled and just like that he was gone.
"I don't like cows any more," Nat said grumpily.
