Friends play an important role in everyone's life. The author describes their best friend Sally, who they met three years ago at school. Sally is medium height and fit, with light skin, beautiful long dark hair, and is very attractive. She is diligent, hard-working, independent, and likes to accomplish things on her own, but is always willing to help others in need, such as helping the author with a math problem without hesitation. The author feels fortunate to have such a true friend as Sally and wants to remain friends with her forever.
