There is a stereotype held by many Americans (this itself might be a stereotype) that British people are intelligent, polite, friendly people. This, of course, is not true. We are as stupid, rude and unpleasant as any other group of people in the world.
Why Americans might think this, I don’t know. We might venture a guess that it’s because they don’t encounter us much, there being only 10 passport holders among them. But that would be stupid and incorrect, too: we’ve swamped their TV screens and films with our actors, and New York, Las Vegas and other major US cities are now crammed to bursting point with tourists, flush with dollars thanks to the high exchange rate that are busy ruining the locals’ spending power.
But I’m coming to the opposite conclusion. I think that the average American might well be nicer than the average Brit. At least, the ones on reality TV seem to be.
