Trick or treat

It's Halloween tomorrow and the local florist shop has put out a selection of pumpkins.   The tradition of "trick or treat" has come a long way over the last thousand years or so:

"Celts dressed up in white with blackened faces during the festival of Samhain to trick the evil spirits that they believed would be roaming the earth before All Saints' Day on November 1st. By the 11th century, this had been adapted by the Church into a tradition called 'souling', which is seen as being the origin of trick-or-treating.  Children go door-to-door, asking for soul cakes in exchange for praying for the souls of friends and relatives. They went dressed up as angels, demons or saints."  From this Source.

Soul cakes now swopped for Snickers bars.
