Americans are always eager to explain the workings of their government,
but again you should avoid specifics.
National defense and international affairs
might get some people angry.
Finally,
visitors should keep in mind
that Americans pride efficiency above all else.
Utilitarian by nature,
Americans think of almost everything
in terms of units to be produced
in the most time and cost efficient manner.
Although the mentality has served Americans well in the business realm,
the attitude might transfer to the social, as well.
Visitors might find
the strict American timetable too confining,
or perhaps downright rude
when a casual lunch abruptly ends
so the American can rush back to work.
