Why can't I?

Why can't I stop you from walking away?
Why didn't you just turn around and stay?

Why can't I stop these little movies in my mind?
Why didn't you make our stories combine?

Why can't I stop the world from turning round?
Why did you leave without making a sound?

Why can't I stop the tears that I shed?
Why did you leave me here for dead?

Why can't you take away all of these fears?
Why can't I realize you are no longer here.
