The Quietest Thing in the Room
From Bedtime for Frances, by Russell Hoban:
Frances stood by Father’s side of the bed very quietly, right near his head. She was so quiet that she was the quietest thing in the room. She was so quiet that Father woke up all of a sudden, with his eyes wide open. He said, “Umph!”
Replace Frances with 2.5yo Guppy, and Father with me, and you have the scene by my bed at 2:20 this morning. Like Frances, Guppy asked if he could sleep with us. Like Father, I refused and sent him back to bed.
