Guinness sells 10 million glasses of beer daily (but no green beer) and far more on St. Patrick's Day. That's a new phenomenon. Not long ago, all pubs in Ireland closed on St Patrick's Day.
Despite persistent myths, St. Patrick's Day recalls a man who didn't alone convert the Irish, didn't use a shamrock to teach the Trinity, and didn't chase out the snakes. It recalls a man who, simply, loved the Irish.
