In America (and elsewhere?) we have a tradition of trick-or-treating where on Halloween or the night before kids go around the neighborhood in a costume, knock on doors, and get candy. It’s a lot of fun.
But I was well into adulthood before I learned that not all places have kids tell jokes before they get candy. Apparently it’s only the city I grew up in that they do that! Not even neighboring cities do it.
In Michigan’s lower peninsula we had Devil’s Night on the eve before Halloween, where teenagers would wreak havoc on pumpkins and egg or T.P. property, but I’ve never heard of this.
