One-and-a-half years have passed since I arrived in Rome. At first, I was a little bit scared when I was walking around because most Italian people are taller and bigger than most Japanese people. There are also very few black people in Japan. However, I don't feel scared anymore; I got used to living here. Some of my friends were exchange students and came to Rome last September. They returned to Japan around July. Some of my friends are studying opera and haved lived here for a couple of years, but some of them are returning back to Japan to go on vacation. Unfortunately, this means that I don't have many chances to meet with other Japanese people lately. I'm a little lonely. The only good thing in this situation is making progress with my studying.
