Out of the mouths of Babes

T-Bird: Mom, which is your favourite princess?
Me: Lady Di.
T-Bird: Who is that?
Me: When I was a little girl like you, Lady Di was the most famous princess in all the world.
T-Bird: And was there an evil witch?
Me: Um. I guess so. (Images of Helen Mirren fill my mind)
T-Bird: And did she live in a castle?
Me: Uhuh, she lived in a place called Buckingham Palace. It's in England.
T-Bird: Wow. That's so cool. Hey, Air?
AirBear: Yip. And you know what?
Me and T: What?
AirBear: If you fart, it keeps you warm.

Shocked silence.
