Thirty teenage exchange students from Denmark and the United States were interviewed concerning the differences they perceived in the two cultures. Salient differences were cited in the domains of family rules, education and schools, use of alcohol, romantic relationships and sexuality, communication and friendships, ethnic differences and religious beliefs and practices. Sometimes these differences caused problems. For this reason placement of exchange students should be done with care. It is noted that parents in the United States tended to be more authoritative and less likely to give their children decision-making responsibility than were their Danish counterparts. The Danish teenagers enjoyed a great deal of freedom along with the concomitant responsibility. (BZ)
