XYZ is for "Examine your Zipper."
Norah's been forgetful and clumsy lately. At breakfast, as she turns to look at the piece of cereal she dropped on her chair, she hits the bowl with her elbow and spills the whole thing on the floor, she trips over her shoes while putting on her pants and then lands on top of her dollhouse, she drenches herself almost every time she takes a drink of water from a bottle, she can't seem to figure out that you don't have to throw your head all the way back to get the water to come out, but more often than anything else these days, she forgets to zip up her pants. It happens all the time. I think it must be a five-year-old thing.
