It is hard to have ghosts as friends. They do not see the point in eating like you do (did) and they can float for days staring at the same painting, really looking at it. They appreciate things differently from us. And bit by bit you fade away. Ghosts are deaf, because all matter passes through them, they are always in the vacuum of space. Your hearing gets worse and worse until you’re sure flesh-people are just mouthing things at you to mess with you but then someone drops a plate and: nothing. And you should have eaten days ago.
