My maternal grandfather once, about this time actually (c.1979), deinged to 'tell us a scary story', as they were so en vogue at that time. It went something like this:
     Once upon a time, there was an old witch, whom everyone was afraid of. Then she unexpectedly died, mysteries unexplained. On a stormy, windy night, two kids went to visit the unlit, empty grave site, somewhere out of the way. The wind swirling, with distant lightning, one of them summonded the courage to ask: "Old witch, old witch, what made you die?" There was a long pause, the wind howling up behind them, as the rain and swirls increased. The other one then repeated, visibly scarred, "Old witch, old witch, what made you die?" There was, again, a long pause. And the old witch said 'nothing at all', nothing at all!  Repeat. (it helps if your grandfather is the dramatist)
