"Mama, can you tell me about the world?"

*gulp* -- the whole world...? Right now??

Turned out she actually only wanted me to tell her about how the world spins - that seemed a little more manageable! She had asked me earlier in the day where the sun went when it went down. So I had explained that actually, the sun wasn't going anywhere - the earth was spinning around so it just looked like the sun was going somewhere when really our part of the world was just turning away from it.

 I don't think she quite got it the first time, so I used a little visual to help her.  We talked about how it's very dark in space, but the sun makes the things that are close to it, bright. I drew a (not quite to scale!) picture of her two familiar countries on a balloon that happened to float past us, got out our little in-case-of-a-storm lantern, turned off all the lights ... and voila! We took turns spinning our little world around and looking at what was going on in different part of the world depending on whether it was facing the bright sun or dark space.

So there you have it, Anna. I have told you all about the world :)
