Just to break all the debate about the english language, I thought I'd recount a short tale.
I have met many Americans (part of having lived there I guess...) and feel content to have the general opinion that I don't tend to like them. However, to *******ise the ever famous phrase "people are stupid, a person is intelligent", "Americans are a pain, any one American is a decent person".
When I was in halls during the first year of my undergrad degree, half of my corridor was given over to the transient Americans who filtered through on a termly basis. Each of them was very pleasant company. One however, fit the stereotypical loud-mouthed-in-your-face-hear-their-conversation-across-the-country types. Over Christmas she went touring Europe, and one of the first things she said when she came back, and I think, the best phrase I've ever heard from an American, was:
'Americans are SO(!) loud and annoying!'
(or words very much to that effect). Couldn't have come from a better mouth.
