A conversation I had with DS2, on the bike today:
Me: Look at the moon up there.
DS2: Not moon, biscuit up there.
Me: Um. It's the moon.
DS2: Biscuit!
Me: Ok, what flavour biscuit is it?
DS2: Chocolate!
Me: Oh, that sounds tasty.
DS2: Not biscuit, moon!
Me: No, I think it's a chocolate biscuit.
DS2: MOON!
