The Power of Imagination

Love the power of a four year old's imagination.

Playing in an empty play house in John Lewis' toy department yesterday ...

Cherub: "Mummy, would you like a drink?"
Me: "Yes, please!"
Cherub: "What would you like?"
Me: "Ooh! Coffee would be nice."
Cherub: "Sorry, we don't have coffee."
Me: "What do you have?"
Cherub: "Just water and apple juice."

Why would she have imaginary juice and water, but no imaginary coffee?
