Car Conversation

This past week, i pointed out some cloud formation to Max as we traveled down the road.
His response stunned me.
i don't know whether he noticed the particular formation i was pointing out.  i don't even remember what it was now.
Max said, "Sky in clouds."
Huh?  But Max, you know the clouds are in the sky.
i looked again at the clouds. (Hey, i was driving.  i couldn't keep my eyes on the sky!)
OH.
"Yeah, Max.  You're right.  There's so many clouds in the sky that it looks like just a little sky in the clouds.
Is it just mom's pride, or is this different way of looking at things a sign of intelligence?
