what's behind you?

Have you ever wondered what the late night sounds in the graveyard were? Or when you are alone in a house but poping sounds come out of no where. I live in a house like that with its own private graveyard, home to over two thousand souls. Being a botanist has its perks. I have always wanted to have a graveyard, since I was a little boy. Not the most normal dream in the world but it was mine and mine alone.
