I visited Exeter University in the summer of 1975, and the brief intercourse this entailed with British youth culture led me to the observation that we ARE the Brits, with minor variations that tend to make this fact obscure to us. Take for example, Bugs Bunny. Qunitessentialy American, right? But British through and through, if you look deep.
G. B. Shaw said it, "One people, separated by a common language."
I've never believed that, but you've had more exposure to them in their batural habitat, while I've encountered quite a few Brits in the wild (America). Can't say I cared much for 'em, tho' that may be my Irish ancestry coming through. Fell very hard for one British girl, but was lured away by an Aussie... :P
Er...AHEM! That would have been a bon mot from Oscar Wilde.
