skeleton

I can recall very little, but:

I'm a ghost, haunting a school which I've never been to. The school's cafeteria area has the make up of an aquarium. I enjoy messing with people, and as I walk past those who are still living I see them get cold shivers. I do something along the lines of that for a while before I meet a girl who stares straight at me. It scares me, before I realise she can see me.
All I remember about her is that I was very happy to see her, or for her to see me.
