formal constraints

One hundred forty syllables suffice
for those who'll spend the effort, and the time
to choose each word with effort (not with dice)
within constraints of meter, and of rhyme.
Communication takes two of a kind
whose inner lexicons contrive to synch
but certainty that there's another mind
rests more on faith, than arguments one'd think.
Elizabethan sonnets set one norm
for Dryden, Shakespeare, Coleridge, and Donne.
Ideas run wild, while hewing to the form.
But some seem unconvinced this could be fun.
Some other life, I may be one of those
content to dream in monochrome, and prose.
