The scene: evening, bedtime. I wander into the living room, looking for boys so I can tell them to get in bed. Firstborn is sitting on the couch, fiddling with his Kindle Fire. Secondborn has ninja'd himself into invisibility by hiding under the table. Beautiful Wife, like Firstborn, is on the couch.
Me: "Ah, good. There is Firstborn. Now, if only I could find Secondborn."
Beautiful Wife: "He is brushing his teeth."
Me: "I was just coming to tell him to brush his teeth. I will look for him in the bathroom."
I leave the living room and look in the bathroom. It is, of course, empty. Secondborn is a righteous ninja, but he hasn't actually mastered teleportation yet.
Me: "He is not brushing his teeth!"
I return to the living room.
Firstborn: "You sound like a character from an Elephant and Piggie book."
Me: "WE MUST BRUSH OUR TEETH!"
Firstborn: "I have given you too many ideas, and by that I mean 'one'."
