I am sad because my summer vacation has finally ended. I had a relaxing summer this year. I went to a zoo with my aunt, had fireworks with my friend, and saw my favourite artist (perform) live. I had a good time. However, I could not get up early and did not exercise, so my days weren’t healthy. （I am not lazy but my home was very comfortable.） Even so, my days were less stressful than usual, so I enjoyed my summer. This fall, I will study hard, because I am taking more courses than I imagined I would. I am worried that I might burn out and my grades will be lower.
