If you could wish for anything, what would it be? Dinosaurs to eat? Money to spend? A Nintendo to live in?
The kids in E. Nesbit's story Five Children and It are bad at wishing. Like, really bad. But that means we get to have fun at their expense and perhaps learn a little bit about the perils of cutting corners.
Also, if anyone finds out what Andrew would wish for if he met a genie, please tell us. The world needs to know.
