Why Saint-Patrick's Day?

Happy Saint Paddy's Day everyone! I will not be able to celebrate much this year sadly, because of this and because I am still recovering from a cold. But I am sharing with you two pages from Charlie Brown's Fourth Super Book of Questions and Answers. It gives you a lot of info about Saint Patrick's Day, and it's aimed at children, so it should also be a reminder that today is not only about drinking (although that can be fun too).
