In the United States, Halloween is celebrated by children dressing up as their favorite characters or people and going house to house to gather candy. They carry around a bag and at the end of the night they count their candy and trade with friends. When I was little, my friend had a magical friend called Halloween Henry. Every Halloween Henry would get half of her candy and would in return give her a toy. This was jut an idea, but trick-or-treating is mostly the only way people celebrate Halloween besides dressing in costumes.
