I once read a book on witchcraft in the Elizabethian period. It was a time when civilizatation was short on science and people looked to superstition for their answers to their woes.
But the practices are still to this day carried on. The fact that we still say "God bless you" when someone sneezes would be construed as witchcraft back then. It would be acknowledging that an evil spirit just left a body and considered a spell.
Good chance you would be headed for the dunking tank after that flippant remark.
Quite possible... Would that have made me a witch? This is really starting to resemble the Monty Python skit now! LOL!
