My Sister-Xie Ni I have a sister who is 10 years old this year. Her name is Xie Ni. My sister writes. She has big eyes, small mouth and black hair. My sister is not as beautiful as me, but she is gentle and amiable, and treats others with humility. I once went to my sister's house for the summer vacation. As soon as I arrived, my sister took out all the watermelons and grapes to entertain me. I usually like watermelon best. When I see a watermelon, I pick it up first, and then I only eat one piece. I was about to pick it up and eat it, when suddenly I saw a watermelon in my other hand. It's my sister. I heard my sister say, "I'll give it to you." I picked it up and was about to eat. My mother said, "Yao Yao, you have eaten so much. Give it to my sister." I gave my sister the watermelon in my hand again. But my sister said, "You can eat if you like." I finally ate that watermelon. That's how my sister treated me. My sister's composition was written in grade three of primary school. I know that I must learn from my sister's advantages, at the same time carry forward my own advantages and strengths, overcome my own shortcomings, and strive to become an excellent person.
