Shirley is my best friend. She is not very tall, but she is lovely. She has long hair, and big, bright, smiling eyes. She often smiles. It makes her look nice. She is my deskmate in Grade 5. During that time, I knew she was very helpful and polite. When I worried about something, she always helped me. She was a top student in our class. One day, I was thinking about a Maths problem. She said, "Can I help you?" "Yes, this problem is too difficult, I can't solve it." I said. "Don't worry, I will teach you." Then, she took her book and taught me, but I didn't understand. She said again, but I still didn't understand. So she said again and again. At last, I understood. I thanked her very much; she said with a smile, "That's all right. Aren't we good friends?" She is my good friend, Shirley. Do you like her?
