The other day, in the car:
Chloe: Why aren't there any lines?
Me: Any lines where? Whaddya mean, lines?
Chloe: Why aren't there any lines, mama?
Me: I don't know what lines you mean, Chloe.
Chloe: Yes you do: LINES!
Me: No, I don't know what lines...what lines where?
Chloe: Lines behind the cars?
Me: There aren't any lines behind the cars...? Why are you looking for lines behind the cars?
Chloe: The cars are going fast...why can't we see the lines?
She was looking for the lines that illustrators use to show motion in a picture...having recently found out that the lines behind a car represent going fast, she wondered why she couldn't see them behind the cars we were passing on the road!
