Mr Prime Minister, sir.
The reason I am voting Yes is not that I want to, in your words, "give the effing Tories a kicking".
As you may be aware, this is not a by-election, or a meaningless protest vote based on emotion or anger. The long-term future of this country is at stake next Thursday.
It is for that reason that I am very calmly voting Yes, to ensure that Scotland is never again ruled by a Tory government it didn't vote for.
Can you understand the difference? Take your time.
