What Uncle Rob Says

Uncle Rob says,
That once on a time the fire flies
Were stars with the others up in the skies.
They used to shimmer, and dance and play,
Night after night in the Milky Way.
But when their papa, the stern old Sun
Said "off to bed with you every one,"
These bold little stars refused to obey,
"Let's hide in that cloud and then run away."
"Let's run to the earth," these bad stars said
"We are quite too old to be sent to bed."
So then they were exiled out of the skies,
And that's how we came with the fire flies,
So Uncle Rob says.
