My hobby is rock climbing. I’ve been doing them for two years. In the beginning, I wasn’t very good, so I’ve gotten much better. I started rock climbing in junior high school. On first day, I felt high nervous, so I only climbed low rocks. It was hard, but very interested. So I kept on work, and now I could climb very fast. I like rock climbing because of it helps me stay in shape. It’s also a good way to make friend. I’ve met a lot of people. We climb, but we also hang out and spend time doing another things now.
