The teacher had a little green owl on her desk. Mi buhito, she called it. My little owl.

She brought it around the room for all her pupils to observe. And then she stopped in front of Andy and Caleb and held it out to them. They waved at it. "Hola."

The owl stared back. It didn't answer. Of course not, it was a plastic owl.

And its big eyes stared at the whole class the whole day.
