BIG – or – little?

BIG or little Fiddle Diddle,
First or Last or in the Middle?
Words upon the Page they Seed,
Which Ones are the First you Read?

Tiny can be Sizable,
Jumbo Short advisable.
Scant so Vast you cannot See,
Huge the Brief down To his Knee.

Slight to Large her Taste in Clams,
Vast to Short for Earthen Dams.
Petite the Rat until it’s Fat,
Ample bugs – Tiny when Splat.

BIG or little – (Think it Through),
Why I Wrote This – HAVE NO CLUE?
