"You can't go to preschool today, honey."

"Why not, Momma?"

"Preschool is closed today."

"Why?"

"Because there's too much carbon monoxide in the air so the Fire Marshall said they had to close until they figure out how to fix it."

"What's carmony..., what's carbide... what's that?"

"It's a gas. Which means it's in the air but you can't see it. And if there's too much of this certain kind of gas and we breathe it in we could get sick or even die."

"That wouldn't be good."
