I'm anxious to read the guide, but I think it boils down to American's making an effort:

- Effort to learn simple greetings/thank you's (bonjour madame, grazzie, gracias, etc.)

- An effort to try new things when abroad (ie: no McDonalds, Hard Rock, Starbucks, etc.)

- An effort to step off the beaten (ie: touristy) path in major cities.

- An effort to "go with the flow" when something is not like it is at home (small hotel rooms, slow service, disorganized lines, no credit cards, lack of napkins are all things I've heard Americans loudly complain about in Europe)

I know I'm preaching to the FT crowd, but maybe the World Citizens Guide can be a required read before a passport is issued or put in a seat pocket on Int'l flights?
