David is craning his neck, trying to look over the long white wall of the bathtub. “Rose,” I say, “David’s looking for you.” Rose is sitting on the stepstool by the sink bent over her library books. She looks up. David grins and splashes the water. Rose goes back to Bob the Builder and David starts looking again. Everything in his body says, “Where is my sister?” She looks up and gets the big smile. Then she decides to really give him a treat. She crouches by the side of the tub and sings, “Jack in the box, Jack in the box, sit so still. Will you come out? Yes! I will!” Up she pops and David laughs hysterically.
