Halloween is a yearly celebration observed in a number of countries on October 31, the eve of the Western Christian feast of All Hallows and the day dedicated to remembering the dead.
Trick-or-treating is a customary celebration for children on Halloween. Children go in costume from house to house, asking for treats such as candy or sometimes money, with the question, "Trick or treat?" The word "trick" refers to "threat" to perform mischief on the homeowners or their property if no treat is given.
Halloween provided an opportunity for real strenuous fun. No real damage was done except to the temper of some who had to hunt for wagon wheels, gates, wagons, barrels, etc., much of which decorated the front street.
