Wandering Accent Syndrome

Both Fi and I suffer from Wandering Accent Syndrome. Which is why Fi always seems to plop an "Aye" in an otherwise very English sentence. And it is why I always seems to do the same with "nooo eh nooo".
I love accents. Not for the aesthetics. Just because they are very cute & quaint. Although you can't call Liverpudlian, Glaswegian or the Brummie accent even remotely pretty, they are incredibly... quaint.
But I think I stepped on a few toes yesterday by saying Glaswegian is the Cockney of Scotland. And I'm still in doubt whether it was the reference to something English or the actual comparison that did the insult. Feel free to enlighten me ;-)
