i am just a shadow

Why do you try to leave me alone
I am not so scary i am just a clone
Which comes when sun are arise
Its depnd on you that what is my size

I am scares when your heart is hollow
Please don't afraid i am just a shadow

Do you think that you can get rid of me
No anyone can't do that or let see
Run so faster and faster and stop and look
I am also run with you like a hook
Sorry but this is my compulsion to follow
Please don't afraid i am just a shadow
