“He looked over at Zero sleeping near him. Zero's face was lit in the starlight, and
there was a flower petal in front of his nose that moved back and forth as he
breathed. It reminded Stanley of something out of a cartoon. Zero breathed in, and
the petal was drawn up almost touching his nose. Zero breathed out, and the petal
moved toward his chin. It stayed on Zero's face for an amazingly long time before
fluttering off to the side.
Stanley considered placing it back in front of Zero's nose, but it wouldn't be the same.”
