Have you ever been to the United Kingdom?
Yes, I have. I've been to England, specifically. It is separated from continental Europe by the North sea to east and the to west, the English channel
Wow, thats specific information!
Yeah. The UK includes the island of Great Britain and the north eastern part of the island of Ireland and many tinier islands. 
That's a lot of islands!! How neat.
These are the British Isles. They consist of over six thousand smaller isles.
I never knew there were so many, fascinating.
Neither did I. Their combined population totals to a whopping 70 million!
That is a lot of British people!
That's the population just in the British Isles. The country is the fourth most densely populated country in the EU.
