"I have a lot of friends, but my best friend is Anh. She is one of the classmates. We have known each other since we were six years old. She has a short black hair, and it is straight. Her lip is small, but it is very beautiful. Her eyes are very affectionately. She is tall and thin. She is very kind and generous. She spends her free time doing volunteer work at a local orphanage, but she is a hard-working student who always gets good grades. Unlike me, she likes sports very much. She plays badminton very good. I am very pleased (delighted) to have such a kind and understanding friend like here. I wish our friendship will last forever"
