Do you have any close friends? I think every body at least has one close friend in their life. And so do I. I have two close friends: Ly and Lan. We are in the same class at the primary school, and then secondary school. We are also neighbors so we spend most of our time in learning and playing together. Ly is a beautiful girl with big black eyes and an oval rosy face. She is an intelligent student who is always at the top of the class. She likes reading, and she often goes to the library whenever she has free time. Lan isn’t as beautiful as Ly, but she has a lovely smile and looks very healthy. Lan is very sporty. She spends most of her free time playing sports. Lan is a volleyball star of our school. She is also very sociable and has a good sense of humor. Her jokes always make us laugh. I love both of my friends and I always hope our friendship will never die. 1. The writer has two close friends. 2. They are in the same class for a long time. 3.
