The green dinosaur was balanced on a book, and Christopher was trying to understand the rules of a game that seemed to have changed twice already.

“Can Samantha play?” Christopher asked.

Timothy looked up at me.

“She has to have the blue one.”

“Is the blue one friendly?” I asked.

“He is if you feed him.”

Christopher laughed.

I sat down beside them, accepted the dinosaur, and asked what happened next.

This time, nobody needed to guess what I would say before letting me into the story.
