An old Celtic tradition for Samhain is a silent supper. Set an additional plate at the table to represent welcoming your ancestors to join you, and put a little of everything being served on the plate. Say a prayer of thanksgiving for the food and fellowship, and then eat in silence to honor the deceased loved ones. After the meal, take the food that's safe for animals from the "spirit plate" outside to share with the four-leggeds, winged, and crawling people.
