I’m very confused, because a couplet is a pair of lines that normally rhyme and have the same meter, and I absolutely despise rhyming poetry so I never use it. I know couplets don’t always rhyme (although they usually do), but I never pay attention to meter either because I think that’s completely unnecessary. So I don’t write my poems in couplets….at least not intentionally?
To answer your second question, I always finish my poems in one swoop because I dislike having several unfinished pieces sitting around.
And thank you! :)
