Me: "But mountains don't talk."
Lily: "Some mountains do."
Some time later...
Lily: "What exactly are mountains for Mummy?"
"You don't eat bottoms Mummy, they are big and smelly."
Just before bed, having 'built' a pram out of towels and blankets:
Lily: "I'm in my pram."
Me : "Oh, going anywhere nice?"
Lily: "Yes, I am going to a lecture on poorly seahorses."
