I have many pen friends. Some live in Japan, some live in China, American ans England. But between them Kumuchi is my closest friend. She is student from Japan. She wants to be a doctor. She is going to medical school next year. It's a 6-months course while in other universities courses last four and five years even only three years in some colleges. She knows taking care of paintents is a difficult job but she likes working with people, and she likes the idea of work in a caring profession. Another main reason that make her want to be a doctor is she has a younger brother and he is in bad health since he was born. Kumuchi always look after him. She hopes that she will find the cure for her brother's sick. I often wish her brother were fine.
