Cameron was so sincere there that he had to glance down at his notes to tell us how special the UK was.
It is certainly true that, by lying about silly things like roaming charges for phones; the end of the postal system; that Doctor Who and Easterners would be a thing of the past; that you'd need to get a visa to see your "foreign" granny in Berwick, if you could get through the barbed wire border; or that we would need to redraw the Treaty of Vereeniging 1902 and 10 million others, they have made people dubious about everything that they say.
It would be ridiculous to imagine that independence will be seamless, but probably to the average person it will appear that way.
You'll still have an (EU) driving licence, although it will probably be issued in Aberdeen (if they let us within the city limits) or Inverness instead of Cardiff, and you'll still have to pay your road tax, although it will be to Edinburgh, not London, that the money will go. But you'll still do it through the bank, or at a post office... and yes, post offices will still exist. Because they manage this kind of thing in other little countries, and we may not be any brighter than the Icelanders or the Irish, but we are also no more stupid.
Afterthought: I just read that the head of GKN, one of the UKs biggest companies, sways that he isn't in the least worried about Scottish Independence, but does go on to say that Cameron's in/out EU referendum is causing great uncertainty.
Terrible when things you say come back to bite you on the backside, Dave, isn't it?
