Halloween in North America
In North America people believed that it was bad luck for a black cat to cross your path. It was believed that it was unlucky for a black cat to come into their homes or travel on their ships.
In the United States trick-or-treaters are welcomed by placing lighted pumpkins known as jack-o'- lanterns in their windows.
The North American tradition of trick or treat comes from the original idea that you must be kind to dead ancestors or they will play a trick on you.
