I was thinking about the impression that American's have good manners (with respect to driving) and I realized that we have such good manners, not because we are nice, but because we have strictly enforced traffic laws.
Here's a damned interesting thing I and my American coworker and my half American self kind of hit upon this today just in shooting the shit.
we are very, very big on assigned seating.
She is a Boston University student. She notices that non-Americans aren't picky about where they sit, but Americans are, since BU has a fairly nationally diverse student body. This came up because of seating at work quirks. I helped confirm this. My Gen Bio II class is in the same room as my Gen Bio I class. They're on entirely different days, at entirely different times, and with a different professor, but the commonality, aside from Gen Bio II following Gen Bio I, is that both classes I got are in room D301. I sit in the exact same seat as last semester, and I made sure of that. I am the ONLY person in Gen Bio II who sits in the back row, and I only chose the back row last semester because I screwed up the schedule and came a week later than most others.
