The Noticer

I am the Noticer. I am the part of you that is never switched on. Nobody notices me... But I notice them. I watch them through every second of the rest of there short lifes. I don't haunt people just follow them. I can't explain myself, it's what I am. You could leave me in a room for ages and I would be fine just noticing what it happening. But I have been based in the worst place on earth, the Hospital, more specifically, the cancer ward...
