In your head

I'd been playing "I spy" with a little kindergartner on the bus every morning, but he was having a hard time sticking to one object. Too often he'd say something like "I see something pink" and when I gave up (since there was little pink in sight), he'd look around himself to find what he could have meant. So, I was explaining that he had to choose the object first, then the say the color.

Me: First you pick the item and then you say the color.
Leonce: Huh?
Me: You find the thing, and you keep it in your head first. Then you can say "I spy something pink."
Leonce: .... My brain?
