Although I'm an American living in Germany, I was just enchanted by the (real) English language on a recent trip to London. So much so that I want to try to "pick up" British English as it were. Not so much the accent(I cannot try to imitate a British accent without coming off like a jerk) but the British English words and mannerism(over say American English) Would people care? Or would they just think I'm being a jerk? How can avoid eliciting such opinions?
