I remember one summer vacation, my brother and I lived in my grandmother's house. One day, my grandparents are going on a business trip. Grandma said to her brother when she went out, "I'll entertain guests at home later." And what my brother heard was "write a composition at home in the future." He actually wrote a composition with relish in the study. He is so devoted, so serious, so dedicated. I looked at him, only to see him brush like water for a while, frown for a while, almost forget the time, forget everything, forget someone around him. After about half an hour, I remembered the doorbell. I immediately stood up and opened the door. I was afraid of disturbing my brother, so I asked the guests to sit quietly next to him. My brother certainly didn't find any guests, and all the guests were attracted by his expression. He praised his brother with his thumb. After he finished writing his composition, he seemed to wake up. When he found a guest coming, he quickly got up and apologized to the guest. He made a good impression on the guests.
My brother is such a person: studious and persistent. He is a good example for me to learn and a man worthy of my admiration.
