This essay examines the differences between Arab and American cultures in their concepts of friends and strangers. In Arab culture, there is a large gap between friends and strangers, while American culture does not make as strong a distinction. Some key differences discussed are that Arabs expect more loyalty, duty and reciprocal favors from friends compared to Americans. Additionally, Arabs share more personal information when introducing themselves and expect more frequent visits and reciprocated invitations from friends than is common in American culture. The text concludes that the concept of friendship holds more serious obligations in Arab culture, and suggests learning about cultural differences to avoid missteps when living in a new culture.
