Roses are red,Violets are blue,Some poems rhyme,Some don't.
I have no idea who the poet was, but every time I read it, it makes me smile.
Writing a poem can help you improve your vocabulary and your writing skills. So try writing one. It can rhyme, but doesn't have to. It can be short or epic. It can be funny or profound. Try a haiku or a limerick or maybe a rap song is more your style. Put your heart into it and make it your own.
