Grammar GeekJCDenton, when the child says "Trick or treat" the person who opens the door gives out candy. There is no "trick." If you don't want to give out candy, you just leave your porch light off. It's an understood system. If the light is on, ring the doorbell for candy. If the light is off, leave the house alone.Thx GG.
