Haunt

Posy's spooked and a bit stressed-out. At first we take no notice, this being our usual Monday morning state of grace after all.

"I think my flat's haunted," she says at last.

"Haunted?"

"By my grandfather's ghost."

"You've only just moved in; why would he haunt your flat?"

"I've got his old photograph album. He keeps switching the lights on and off."

"That doesn't strike me as much of an afterlife, switching lights on and off. I'd want something more interesting than that if I was a ghost."
