We were out of milk this morning so the kids had water instead and Sam asks us how come we always have water. So we have a little discussion about there being pipes connected to the house that bring us water.
Hazel: How come they don’t have milk in them?
Me: Good idea! But I don’t think we have enough cows to supply everyone that much milk.
Sam: Yes there are.
Hazel: And there are goats too!
