I hope you won't use an umbrella in a thunderstorm O.O

The reason sky is used is because it represents something. There is a meaning behind the poem, as it is about my confusion in life right now. The sky represents the future events and/or the truth. The clouds are the things making me unsure of myself, the lightning the anger and hate from the clouds, and the rain is the thing i am trying to use to hide my sadness and tears.
I personally think sky mentioned this way was alright, i wasnt writing this for a general quallity but in my own style as a poet and the fact that i wrote the poem with a deeper meaning in mind to vent some of my frustration at the time.

I see where you could be coming from, and I don't mean to sound snippy trust me. With my style I tend to reuse a word when it's meant to represent a theme or object that's important to the poem. In this poem, my confusion is blocking my future and happiness, which is represented by the clouds and the sky in turn. My personal feeling is that editing a poem takes away from the poet's style and feelings, I don't write with a rubric because it makes me feel limited. The only time I use a rubric is when I write a haiku(spelling?) or want to keep it in rhyme.
