I was reading Aiden his story. It was his 'planets' book. At the end, there is a questions page which he makes me read...

Why is the earth blue?

How can you spot Mars?
How many moons has Jupiter?
Then he asked ME a question...

"How many planets are there?"
"nine", I said
"No there's ten now"
"How do you know?"
"I saw it on Newsround, they've built another one..."
