Compared to what i see as the average American mentality, here in Britain, there is a lot of "can't do" attitude.
America is still a teenager. Impatient, aggressive, reckless, thinks she's always right. Yet she's optimistic, hopeful and energetic. She still believes she is invincible and can do anything.
Britain is older and wiser, but also more jaded and cynical. She's been there, done that and now has to watch as others make the same mistakes.
