There’s Gotta Be Nourishment Somewhere

Small spider on ceiling recon,
There aren’t any flies in this room.
Somewhere in this empty boxland
You’ve got to be finding food.

See how well a human mind works?
It will observe and then deduce.
Doesn’t work as well as spiders,
But every life’s a living proof.

Earth’s surface is mouth parts, a tongue,
A roughed but sensitive sensor
Of papillae brushing through night
For any edible splendor.
