Poetry is something different to everyone! Some people like poems to rhyme as I do, some like them to be deep and make you think, some just enjoy the rythmic movement of the words on the page! There are many different ways of writing and enjoying a poem. Some are short, some are long, some haiku's are beautiful and only a few lines long. What ever way you like your poetry, know that none is wrong. If you like it, if you express your feelings and you feel better for it. You can't be wrong.
Write your own poem, try it today, see how you feel afterwards!
