Why does the sky end
Precisely at the horizon?
Surely the sky is powerful enough
To go where it will.
By rights it should
Lap over onto land,
Or slip into the sea.
Why does the sky,
Being infinite,
Have to end at all?
How came it to let
The Earth intrude?
Perhaps the sky,
Being wiser than we,
Knows where its domain must end
And ours begin.
