"Give it to me! Give it to me!" Nell shouted, furious to see Harv's 
hands on it. Harv amused himself for a second playing keep-away, then gave it 
to her. She ran to the room that she shared with Harv and slammed the door as 
hard as she could. Dinosaur, Duck, Peter, and Purple were waiting for her. "I 
got us a new bed," she told them. She grabbed her old crib mattress and heaved 
it into the corner, then unfolded the new one precisely on the floor. It was 
disappointingly thin, more blanket than mattress. But when she had it all laid 
out on the floor, it made a whooshing noise—not loud—the sound of 
her brother's breathing late at night. It thickened as it inhaled, and when it 
was done, it looked like a real mattress. She gathered Dinosaur and Duck and 
Peter and Purple up into her arms and then, just to make sure, jumped up and 
down on it several hundred times.
