Linda is my best friend。 She has changed o lot in the past two years。

　　She used to be short and have short hair。 However， now she is much taller than before。 She has long hair。 She used to like playing ping-pong， watching TV and chatting with friends。 But she likes playing the piano， reading books and taking a walk now。 She used to be outgoing。 Now she is a little quite。

　　I think people sure change as time goes by。 Even though she has changed a lot， we will be the best friends all the time。
