W: Good evening! Welcome to our Talk Show program. Our guest today is Mr. David Smith, who had the experience of studying abroad for seven years and then returning back home. Well, Mr. Smith, do you think going abroad was the hard part?
M: I don’t think so, but returning back home was really hard.
W: Why?
M: Well, for many students, returning back to their home countries can be a very confusing experience called Re-entry Shock.
W: Re-entry Shock! That sounds quite interesting. Can you explain it?
M: For example, many students who come to the United States experience freedoms they have never enjoyed in their country.
W: Sure, such as freedom from family, freedom from cultural norms they didn’t like and freedom from the pressures of working in a real job.
M: However, too much freedom and unstructured life can lead to other problems. Students sometimes skip classes, stay out late, and engage in activities that their families and cultures might not approve of, but students want to enjoy "freedom" while it lasts.
W: So when students return back to their countries, they can struggle with fitting back into the cultural norms and family expectations of the past.
M: Yes. Naturally, depression is possible and a loss of self can be resulted.
W: Then what can students do to minimize this Re-entry Shock?
M: First of all, keep in contact with your family and friends while you are abroad. They will be your first source of advice and support once you return.
W: What else?
M: Second, have a clear plan what you will do when you return. Start looking for a job now or apply to enter a school months before you return. Re-entry Shock can be the greatest when you have nothing to do when you return.
