The Great Britain Confusion
First, we have Great Britain. It’s an island. It’s not a country, but it contains three countries: England, Scotland, and Wales.
England: Famous for tea, the Royal Family, and losing football matches.
Scotland: Famous for kilts, whisky, and inventing most things, including modern engineering and bad weather.
Wales: Famous for having a dragon on their flag, a language with far too many vowels, and beautiful landscapes, but they often get forgotten.
Now, throw Northern Ireland into the mix. Northern Ireland is not on the island of Great Britain, but it is part of the United Kingdom. If you say "Great Britain" and include Northern Ireland, you get the United Kingdom. If you say "The British Isles," you include the whole island of Ireland, which makes people in the Republic of Ireland very, very angry, because they are a separate country.
Here is the best part: Scotland, Wales, and Northern Ireland have their own parliaments, their own first ministers, and sometimes their own laws. Yet they all answer to the Parliament in London. In the Olympics, they compete as "Team GB," which is a lie because it includes Northern Irish athletes. In the World Cup, they all play as separate countries. So you can cheer for Scotland to beat England, while simultaneously sharing the same Monarch.
