Re: The King's English
"King of Greece for half a century or so. Close enough?"
Being King of Greece doesn't actually make you Greek (OK: of Greek descent). He may have been but maybe not - no idea and I can't be bothered to look it up because it isn't important: I know how European Royalty works. When you run out of Royals, you get an obscure Germanic mini state to send over someone.
Capital G on granddad? Are you sure you aren't German? Proper nouns and certain honorifics only please! Mind you I'm a granddad ... should I demand a capital G? I'll ignore the d vs dd bit ... 8)
