?

I'm a walking question,

a puzzle personified.

A need for retrogression,

others said their minds.

Withal, my state's the same

for I know

I've been and always will be

an unbroken case,

an unsolved riddle,

a long hurdle,

a jargon,

a between-the-lines,

an uncracked code,

a baffling stumper,

a head-scratcher,

a perplexing mouth,

a labyrinth,

a possible hark,

a constant,

a question mark.
