Dear Michelle,

    My mother is not a good example for me and my sister. She smokes, stays out late, and she curses (咒骂).

I love her but I am ashamed of her. I do not want to bring my friends home because she does not act like any

of the other mothers. She says I am a loser because I sit at home and study. I wish I could live in another

family that was normal, but it will be 5 years before I am 18. What am I supposed to do until then?

                                                                                                                     Prisoner of a Crazy House

Dear 7th Grader,

    I am glad that you love your mother because the rest of your feelings about her may change as you get

older and mature.

    While it is true that your mother's smoking, partying and cursing bring you shame, the fact that you want

to stay separate from her doings is notable and very smart. It shows that you are a winner, not a loser. I am

guessing, therefore, that you do not bring shame to yourself, and that is a good thing. So, keep it that way

and keep away from your mother's habits. 

    At the same time, try to get the best grades and join clubs and school activities. Offer social service on

weekends and visit your friends at their homes.

    Fortunately, you are not alone. Many teens live in homes with immature, misguided, selfish parents. But

they develop good friendships with nice kids, do well in school, and often find a teacher or guidance advisor

who makes all the difference!

    Do it, Miss Winning 13 years old, and keep looking forward to your own future. Maybe by then your

mother may even see the light and realize how good you really are.

                                                                                                                                          Michelle
