I'm not entirely sure where this question originated from, but I saw it earlier and it piqued my interest. For me, the answer was immediate – I would rather be a poem.
Novels have this sense of completion I simply wouldn't want. A poem is, almost always, more ambiguous. Poetry is packed full of imagery, each word loaded, and placed for a reason. Some could say poetry's short and sweet – although, the 'sweet' aspect is definitely questionable, and so is 'short' in a lot of cases. So, frankly, I can't pinpoint exactly why I'd prefer to be a poem – is it the lyrical language? The time capsule-esque packaging of emotion? – but I can say it's what I'd definitely prefer to be. I love novels, clearly, and the pleasure I get from finishing a good book is immeasurable, yet the prospect of existing as a poem is… irresistible.
Besides, is there anything better than "'Hope' is the thing with feathers - / That perches in the soul - / And sings the tune without the words - / And never stops - at all -"?
I'm incredibly interested to hear your thoughts on this: would you rather be a novel or a poem? Currently, I'm reckoning the majority will go for poem.
