So I always thought that the Great Britain, UK, England thing was confusing. I never really bothered with the intracacies of it, but since I have a presentation coming up where I sort of have to know, now was the time to get educated. I soon found that this stuff is crazy confusing. (Seriously.)
Anyway, I found an amazing youtube video that explains everything. And now I know, it's not just me. Britain/whatever is just one big identity crisis waiting to happen.
