Why is poetry important or not important to learn?

Poetry is a good thing to learn in school even though I dislike poetry a lot. It's a good thing to learn about because it teaches us about figurative language and different tones. It helps us understand the English language. It also helps us understand why poets use certain words and phrases. I really don't like poetry and I don't get why poets can't write out what they really mean instead of making us figure it out.
