Last spring, I was fortunate to be chosen to join in an exchange study program. The moment I arrived in Paris, I was greeted by a nice French couple who would become my host parents. The bit of French I had taken in high school began coming out of my mouth; speaking the language would only become more natural over the course of the term. At the airport, we all got into the couple’s car and began the journey to their townhouse. We talked the whole way, getting to know one another.

Every day afterwards, I would eat breakfast with the two of them, and then we’d all go our separate ways for the day. In the evening, my host mother would make delicious dinners for the three of us. My experience was exciting until I received some shocking news from my program coordinator（协调人）: There had been a death in my host parents' family and they would have to go away for several weeks to deal with all the business that arises from the death. That afternoon, I had to move out of one family's house and into another.

The coordinator told me I'd have a roommate and asked whether I would mind sharing a bedroom with an English speaker. To avoid speaking my native language, I asked not to be placed with an English-speaking roommate. When I got to my new room, I introduced myself to my new roommate Paolo, a Brazilian（巴西人）, the same age as I, whom I was surprised to find playing one of my favorite CDs on his computer! In just a few hours, we knew we'd be good friends for the rest of the term.

    I left France with many stories, so when people ask me what my favorite part of the trip was, they always hear about my Brazilian friend Paolo and the weekdays in class, weeknights on the town, and weekends exploring France we enjoyed together. I would recommend an exchange program to anyone who wants to experience foreign cultures and gain meaningful friendships.
