Trick or treating started to become popular back in the 1930s. It was in the United States and Canada wherein people really became engulfed into finding the right costume to wear. This stopped a bit during 1941 because this was the time when World War started. There was not enough sugar to go around in order to create candy.
People do not realize that Halloween has started out back in the 1900s for some parts of the world. Some people say that they are too old for trick or treating the moment that they reach 12 years old. Some would still push to go trick or treating until they are 17.
