As you prepared to study abroad you were probably concerned about how different things would be in your host country and how you would manage a new language and culture. You probably did not worry about those issues as you prepared to come home. But coming home can be as difficult as going abroad. This process of re-entering your home culture is commonly called reverse culture shock.
Many students are surprised to find that they feel out of place when they return.
You discover that you are not returning to the familiar culture you left behind. The small changes that inevitably occur while you are away are not the source of reverse culture shock. It comes, rather, from viewing your own culture through different eyes. Moreover, friends and relatives are apt to be less tolerant of your adjustment difficulties upon your return than they were when you were adjusting to the culture of your study abroad program. It may be hard to find a friendly listener who is willing to try to understand all that you've experienced.
