I never got a glimpse of the young girls, but I heard them--it sounded like two sisters.
They were quite excited about all the recently added items to the play area of our library, and it was obvious that at least one of them had never seen a beanbag chair before.
Older sister: "Wow! Look at all the new additions!"
The young one: "Look at that ball!"
Older sibling: "That's not a ball...that's a silly chair."
