I don't think friends need to be the same. My best friend is Linda. She is very different from me. She is much quieter and taller than me. She always has long hair, but I like short hair. I am good at math, but Linda is good at English and Chinese. We like to do our homework together after school. We always help each other. We both like playing tennis. As friends, I think we should help each other and really care about each other.
