I was lucky enough to study abroad as an exchange student, but this allowed me to improve my language skills and found out more about the local culture. It was my active participation which helped me make the friends in a foreign country. Instead staying in my room, I got out of the house so as not to be homesick. I'll never forget the times when I first went camping with my friends. I also tried something entire new such as a dance class and a walking club.
