On Sunday it's Saint Patrick's Day! Irish people, how is it for you? Other Europeans, have you ever been?

Celebrated it once in Munich and was told it's the second biggest St Patrick's parade in Europe, but don't know if it's true. It was definitely fun, but thanks to a parade member I suffered some hearing loss cause he screamed out of nowhere right into my ear (he was dressed as a viking and thought it would be funny to "scare" people). So no intention going back personally.

And I learned that it's an American tradition partying and celebrating loudly and the old Irish way is a very quiet and serious one, no partying at all. Did it change? Do people in Ireland celebrate the day like parts in the rest of the world?
