Halloween was not created for kids to ask for candy and for adults to dress at parties and drink all night. Halloween was made for the purpose of allowing the order to release many species of aliens that are on Earth. This is their one day of vacation and they are allowed to be around humans because they simply believe they are people with very good costumes. This is the day that they do not have to live in underground labs and we ask them to please return in no more than 24 hours or they will be deported back to their planets.
All aliens that we allow to go out on Halloween are with us because they are seeking shelter from prosecution on their own planets. This is the reason why they obey our requests and have no problem with it. They live in perfectly accommodating installations underground for the rest of the year.
