Right Next To The Chocolate Cows

(My brother, my nephew, and I are on a short road trip. I spot a farm, which I point out to my nephew.)

Me: “Hey, look! Cows. It’s a cow farm. It has the milk-towers and everything.”

Brother: “It’s called a dairy.”

Nephew: “A dairy. Then there is lactose in those towers.”

Me: “… Yeah.”

Nephew: “Except that maybe those are the lactose-free cows that make lactose-free milk.”
