ive a little secret. i dont try to rhyme ;)

theres absolutely no rule in poetry that says it must, its just a style or genre, like punk versus metal. have you ever tried to rhyme in old english? don't try, its like trying to make music with a pick axe..

poems back then didn't use rhyme. Instead, they used alliterative verse and stress-timing. now thats way more than you ever wanted to know ;)
