No it's not your fault. Great Britain is what people have the nickname for the UK. So technically your right, it isn't a country.I'll admit that I'm short on sleep today, so maybe I just need to go back to bed, but I'm having a hard time understanding people today. haha. What does this mean? You said that Great Britain is a country and that it is a nickname for the UK, neither of which are true. I'm sorry for misunderstanding.
