Why is Halloween different than all other days. Because on Halloween you can knock on anyone’s door and ask for candy. On any other day you do this you’ll be shot or the police will be called. Halloween is the one day when signs and laws that say: No Trespassing, No Canvassing, No Peddling, No Soliciting, Permits Required, have no effect. Halloween is the Universal Free Pass Day. You Must Give Me A Hand-Out Day. A day the homeless and the hungry cannot be denied. You can even ring the doorbell of the White House and ask for a hand out of candy.
