Ghost.
I'm a ghost in this world, no one can see me, no one can feel me... They notive me only when I touch someone and after that they forget me, just like I have never been there, they dont hear my voice, even if I shout, when I walk they walk just towards me, they ignore me, I cant fight back, I just run away, it's not brave and I'm not proud of that ... I'm just a ghost in this big world...
