" I know a few things about ghosts. The only way to stop them getting inside you is to spend every second of the day thinking about something else. Fighting like that makes you tired, and it doesn't matter how hard you fight anyway. They chip till they make a crack, and before you know it there's a ghost squatter in your living room. It's hard to get them out. Hard because they settle in. Hard because you like the company. "

― Cath Crowley , A Little Wanting Song
