In Italy apparently when it is pay back time a dead fish is put outside your door (in Ghana someone may pick it and go prepare breakfast with it … unless they understand what the full implications of a dead fish on a doorstep are)

“A life for an eye” philosophy ensures that people are careful before they mess with the lives of others.
