death was coming to a grandfather, he has 3 granddaughters, the oldest says,"Wiat, come back in a week!" death is back a week later, the middle says,"No! come back in a month." a month later death is back, finally the youngest holds up a candle, lights it, and says,"come back when this candle burns out." death leaves, never comes back.
HOW?
