No fire in his belly

We went down to the opening of the new wharf in Raglan this evening, and walked home as the sun was disappearing, a new moon in the sky ("where's the rest of the moon gone Mummy? Silly moon!").  The sky was that twilight blue where the clouds look grey.

Em: Look Mummy!  Why is that a shadow cloud?
Me: It looks grey doesn't it. That's because it's getting dark.
Em: Mummy! It's a dragon!
Me: It does look like a dragon doesn't it?
Em: It IS a dragon.  Look, there's its mouth.
Me: Oh yeah. Do you think it's roaring?
Em: Yep, he's saying RAAAAARRRRRR.  But he doesn't have any fire in his belly so he won't burn us up.
Me: Oh good.
Em: He does have fire in his belly but he won't roar it at us.  He only roars it at the baddies.  He won't hurt the goodies.
Me: Are we goodies or baddies?
Em: Goodies.
Me: How do you know who are the goodies and who are the baddies?
Em: You and me and Daddy and Daddy's friend and Uncle Nick and all those families are goodies.
Me: How do you know if someone's a baddy?
Em:  Um, because, they tries to hurt you.
Me: Do you know any baddies?
Em: Nope.
Me: That must be why the dragon isn't roaring fire.
Em: Yep, you're right Mummy.
