Kinda dumb to put the vase that much in the way and then complain that it got knocked over.
Japanese Ghosts really behave like Karen's, aren't they?
A ghost story of this sort has two parts: a sin, and a punishment. Sometimes the sin can be absurdly small, such as accidentally knocking over a flower vase on the sidewalk, or failing to listen to an old woman's ramblings. It doesn't really matter, since the audience is only interested in voyeurism of the thrilling punishment, buttressed by the slim feeling that you would be safe were you in the same scenario. Perhaps at one time we told these stories as warnings to avoid transgressive actions, but certainly the main point of them now is the blood.
I think despite not being a ghost story, Funny Games (2007) exemplifies and examines this sort of structure. I'd also point to Otherside Picnic's treatment of the ghost story: they're not punishments, you didn't do anything truly wrong... you just got unlucky, as though you were caught in a natural disaster.
