The houses are comfortable and functional, but I don't think the average American considers his home as something built to last for centuries and hand down to future generations. Americans have big lawns and spend an inordinate amount of time trimming them, perhaps a legacy of the felling of trees and clearing of land that pushed back the American frontier. On the job front, I personally appreciated the casual way of dressing, even among management. Suits and ties are rare, not only due to the warmer climate but again to a certain spirit of equality. This is reinforced by the American habit of using first names almost immediately, and the lack of a tu or vous to establish degrees of distance or intimacy.
Conversation is more direct and spontaneous.
In meetings, unlike the usual silent reverence for authority we observe in France, all participants are expected to express their opinion, even if it means contradicting the boss. Americans are plan-oriented, and want everyone involved and fully committed. They are also good at taking personal responsibility and respecting deadlines. Here, we French have something to learn. Food in America is inexpensive, especially the meat.
