Peter felt that she was calling him names, and at a venture he
retorted hotly:

"So are you!"

Then rather curiously they both snapped out the same remark:

"Shut up!"

"Shut up!"

Nevertheless the bird was determined to save him if she could,
and by one last mighty effort she propelled the nest against the
rock. Then up she flew; deserting her eggs, so as to make her
meaning clear.

Then at last he understood, and clutched the nest and waved
his thanks to the bird as she fluttered overhead. It was not to
receive his thanks, however, that she hung there in the sky; it
was not even to watch him get into the nest; it was to see what
he did with her eggs.
