Most people, wear green on this day. One of the Irish traditions is to pinch anyone who is not wearing green on St. Patrick’s Day.
The shamrock, pot-of-gold and leprechauns are also associated with St. Patrick’s Day.
The shamrock is supposed to bring good luck.
The leprechaun is a small Irish fairy. He is dressed like a shoemaker, with pointed shoes and hat. Leprechauns are supposed to be unfriendly little men who lives alone in the forest, spending all of their time making shoes and guarding their treasures. If someone catches a leprechaun, he will be forced to tell where he hides all his pots of gold.
