A ghost was trying to write a letter to its landlord. But it didn’t know where to begin. Practical matters aside — how to hold a pen? the ghost could just about wiggle a book on a shelf and flicker a light, let alone manoeuvre a writing implement; where to buy paper? not even nice writing paper, a piece of A4 would do, or one of those ones from old printers with the holes in the side — leaving those practical matters aside, the ghost just didn’t know how to word it. Sorry Mrs Peterson, I cannot pay the rent this month, I’m too DEAD seemed a bit direct. But what else could you write! It was just all quite a lot. So the ghost decided to wiggle a few books, when it could, and watch the Petersons from the corner, hoping that they’d soon smell the corpse, and be able to get on with finding a new tenant.
