What even I find weird is the custom of sacrificing pigs before Christmas. In small villages, in my country, there is a custom on which people sacrifice pigs a few days/weeks before Christmas. Although pigs are killed all over the world for their meat I wind this practice of brutally killing a pig just before Christmas to be a strange custom. Decades ago and even centuries people had not too many food sources and pigs were one of them. They would grow them for a year and then sacrifice them in winter. For that period of time this activity must have been something natural, but for nowadays I see it as bizarre as one can imagine.
