It's like they almost take pride in differentiation. Throw an international party and the two UKians that show up will have a verbal civil war that puts us Somalis to shame. The shopkeepers maintain their peace with healthy and frequent exchange of muted disdain and murmured resentment. That's, when the other ethnic tonsils are not being inflamed (Scotts, Welsh, and the verile Manx; consciously absent are the clover-wielding gentlemen of the east, left out of the union for my own safety, and to keep membership of my drinking club.)
All good people though. Except the Chavs; a meta-culture of mediocrity that belongs on the next boat leaving for America, to plug the Gulf oil well.
[Edit:
Oh, this seems to have offended someone, most likely a fellow yank. No need to be a hero; piss-taking is a national past-time of the Isles, and its cultural debris scattered around the world, outside the U.S (we have escaped the wit shrapnels I guess) I have deliberately disclosed my own heritage within that rant above, expecting to be paid in kind ;-) When in doubt, stay out of it. It's a bonding experience]
