Halloween is celebrated on October 31st. Children dress up in costumes and go trick-or-treating by knocking on doors and saying "trick or treat" to receive candy. Safety tips include walking with an adult, not eating candy until checked by parents for safety, carrying a flashlight, and wearing clear costumes without weapons or anything that could cause tripping. Popular Halloween activities include trick-or-treating, bobbing for apples at parties, and adults wearing costumes to work or company parties.
