The Silent Shadow

I am nobody but a shadow. When my job is done, people forget me.....I am just a shadow, which stay behind watching people celebrate their happiness even thought things cannot be done without me guiding....Yet, I am great in somebody's eye who can see the real me and know the real me.....those who know me call me.....King Shadow......too bad, only a few knows me well, not even the person who think she is close to me......
