Why
Is the sky?

What starts the thunder overhead?
Who makes the crashing noise?
Are the angels falling out of bed?
Are they breaking all their toys?

Why does the sun go down so soon?
Why do the night-clouds crawl
Hungrily up to the new-laid moon
And swallow it, shell and all?

If there's a Bear among the stars,
As all the people say,
Won't he jump over those Pasture-bars
And drink up the Milky Way?

Does every star that happens to fall
Turn into a fire-fly?
Can't it ever get back to Heaven at all?
And why
Is the sky?
