I think poems are not just written words; they are feelings and emotions converted into letters and metaphors, and imaginative scenarios or events that could decorate that sad or melancholic vibe that they have. Sad, most of mine are simply sad poems, yet they come from the deepest part of my soul. I feel like writing poems for people to read is somehow parallel to telling your story and secrets to the ones who would not judge you but rather relate to you, and cry, or even feel loved after being poured with the mesmerizing message. 
I write more about love. So if you love the idea of love, you found the right heaven.
