Addy: What's up there?
Me: Do you mean the light on the ceiling or are you talking about the sky?
Addy: In the sky.
Me: Well, there's birds and clouds and airplanes, and further up there are stars and the sun and the moon and the satellites and the space station.
Addy: Ooh, I wanna go to the space station. I can fly in a rocket and go visit the space station.
