Miss.Li is a very pretty and kind person. Although it's not a long time since i know her, she has became my best friend. We walking around together, discussing self attitudes toward life and bear oneself.Though our ages have a decade difference, i learned many useful knowledge from her and she treated me like an elder sister. She taught me many principles for being people, how to dressing as a woman and how to exert my advantage and present my beauty.
She completely changed my mind that beautiful girl is more fastidious and overweening. Maybe it's related with her beliefs.
