Letters Versus Me

Chronic
Fluent
Agnostic
Versatile
Tortuous
Unilateral

Words floating through space,
The universe of a song.
No beat is that long,
And the song comes to a close.
The letters fall, and rise again.

Antibiotic
Exotic
Atheist
Heterogeneous
Perennial
Ultraliberal

They just be,
Unlike me.
I fit these words into a puzzle.
