The Smartest Person in the World

"Hey, look at that bird! It's huge!" exclaimed Sam.

"That's not a bird, silly. It's a plane," said Lucy.

"I know it's a plane. I was just testing you," said Sam.

"Well, I passed the test," said Lucy with a smirk.

"You always do," said Sam, looking at her admiringly.

"I'm just smarter than you," said Lucy, playfully pushing him.

Sam grinned. "Yeah, you are. But I don't mind being the second smartest person in the world as long as you're the first."
