No! some do but, it seems we are either too self-deprecating, or too cock sure we are the king of the mountain. Too little ballance at a mean. I've only been abroad once for a few weeks, and saw, in London, for example, so many brassy, cock-sure American tourists out rubernecking and making insulting comments in comparison of things British with things American in a loud voice, that I tried to disguise myself as British, so I wouldn't be thought to be one of them. [And I fooled some of the Americans at any rate.]
