Do an Internet search on international faux pas. Read about behaviors that are rude or inconsiderate in other cultures that you might not find offensive at all.
Write an essay of 250-500 words on what you found. Are these behaviors considered inappropriate in only one other culture or in many? How much trouble could you find yourself in if you did or said these things in your cultural setting? Which culture that you learned about would be the most difficult for you to live in because of their faux pas? What are faux pas in your culture that a person from outside your culture might do?
