The Cloud Unknowing

Strange species of cloud this,

That casts no shadow,
That moves unseen,
Just rising numbers
On a screen.
The odd hit and miss - 
For every secret blow, 
Another is unkissed.
Oh, a cloud that neither,
Rains nor shades,
But heaves with silent breath,
The better to insinuate -
Recumbent lottery of death
For any passing through.
The perfect egalitarian,
(If it could choose)
For anyone will do.
