Knock at the door

So, yesterday there is a knock on the door.  The Mrs. is still at work.  Both girls have recently shot down the hall towards the bedrooms.  At the door was a neighborhood boy, who also happens to be a classmate of the Bear's, and his mom.  The Bear is being invited to the boy's 6th birthday party, an event she'll miss because of a prior engagement (Peter Pan at the Arden with my parents).  Before they walk away, I call the Bear to say a quick hello.  In a flash she is standing behind me...wearing nothing but a smile. 

I really thought I had a few years before she comes to the door naked to say hey to a boy.
