Compulsive Instinct

Addict by birth or choosy do-over
And over and over, decisions contort
To swab the decks of all traces of natural
Fallacies, driving the bus to school at 
Precise times, preconfigured by the
Cells that must respond to ambient
Temperatures and light, and therefore
Cannot be said to know what they do
Or even to be able to hear the question:
Why?
