Why so grey?

I've been asked where all this grey clouds come from? What happened to me that turned me into what I am. Why no smile?
Well, I am different... not special or good. As I covered some of this in my walk I just have different perspectives and another purpose. I do smile. I do cry. I hate and love all the same, just as you do. Just that in my eternal turmoil, I do it to the extremes. While life is almost always grey shaded, my nuances are deep white or dark. Mixing them will get me nowhere else but in this grey zone.
I snap like a tense cable and I swallow resentment that others would find despicable. It is just what and how I am. You don't have to agree with me, and for all sake, you don't have to be like me. All you can do is listen. Listen to something that you might never hear by yourself. A song so sad that will break the stones of the mountains. So deep that oceans could not compete. A linear string of notes uncommon for most of the living ones, but that doesn't require understanding to enjoy it.
So I am nothing else than you, just lit and set aflame different. Just a rock, no more precious or distinct, but formed with other layers of forgotten sand. And we're here just to complete a background for a painting way more complicated and deep than both of us.
