A reply to a letter

　　Dear Mary,

　　I am sorry to learn that you are not happy. Those who treat you badly wont be your true friends, so dont take it seriously. I advise you to avoid her and pay no attention to her joking. If you seem not to care what she says or thinks, she will get tired of making fun of you. I suggest you should not worry about what other people think and feel about you any more.

　　Best wishes.

　　Yours

　　Tracy
