I want to know why a ghost can supposedly throw a glass or move a ouija board or open and close doors but can't type on a computer or a typewriter.
Seriously, ghosties, if you wanted to communicate then moveable type presents the easiest way to do this. Most of you are supposedly created long after the invention of typewriters so it shouldn't be too much of a difficulty to wrap your ectoplasmic head around.
It's almost like there's no such thing as ghosts...
