Ireland is known as the Emerald Isle. Green is traditionally worn on St. Patrick's day to honor the Emerald Isle. Tradition holds that on that day, people who do not wear green are pinched as a reminder to wear green to honor the Emerald Isle.
But you donât have to be drunk or Irish or drunk and Irish to enjoy St Patrickâs Day. You only have to put into it what you hope to get out of it. If that means going to the pub, then great. If that means avoiding everything that even has a smidgen of the colour green in it for the day, then thatâs okay too.
