DARK MAGIC

"What is dark magic, grandma?" asked one of the children. Grandma replied: "Well my dear, sometimes some bad people want other people to suffer. So they cast some evil spells on them. That is called dark magic."
Another child asked: "What if that couple come to my dream tonight and try to cast a bad spell on me?"
"Oh, then you can tell them that your grandma will kick their asses."
There was laughter among the children.
