I wrote a piece of poetry for one of my short stories (the main character, Eri, writes poems). It's the following:
Eri, did you feel the earthquake last night?
Are you really sure your apartment's alright?
In which planet where you wandering when it came?
Is reality and the world as you know still the same?
I have my doubts as to whether to put a comma after Eri. Seems to stop the whole flow. Or maybe that kind of punctuation is invisible in poetry?
