Trick-or-treating is a time-honored Halloween tradition where children dress up in costumes and go from door to door asking for candy. However, in different parts of the world, the activity can go by different names. In the United Kingdom, for example, it is known as "guising" or "mumming." In Ireland, it is called "going around with a turnip" or "Souling." In France, children participate in "la chasse aux bonbons," or "candy hunting," while in Germany, it's "Süßes oder Saures," which means "sweet or sour." Regardless of the name, trick-or-treating is a beloved activity that brings joy and excitement to children and adults alike during the spooky season.
