I agree with Mike on this one, I don't see why you wrote it this way. Couplets are almost exclusively used when they rhyme, which yours don't, and when they contain ideas among themselves, which yours don't. You could easily have made this one stanza, or two; it's not so long that it needs breaks that frequent.
And maybe my math is wrong, but the poem will be eighteen when you're thirty-six. Unless we hit nuclear war, I think we'll still have calendars birthdays and deaths. That stanza is a touch weird.
It's an interesting look at life, if a little out there, but I'm left more puzzled by your form than your content.
I really like this poem, perfect message, it's short and sweet. The only little thing that is annoying me is "Blind Eyelids" surely you mean blind eyes?
Well, first, happy birthday :)
And I love this. It really shows your true emotion and what you think of this world, the possibilities, and what will happen. I envy your writing abilities and the talent of being able to capture raw emotion and provoke thought. I find that complicated to write down my thoughts and try to answer them, seeing as I think about sixty miles an hour... :)
Nice write, I hope to read more.
