读写任务

Hello there,

     I'm writing to ask you for help.It's really urgent because I'm considering running away from

home.I feel like there's no way to fix the problem with my mother.

     Yesterday evening,we had a heated argument at home after I got home a bit late again.

     I had been at my friend's birthday party.I'd explained it to her but she just didn't believe me.

    I do know my mother loves me very much and she wants me around every day,or even every

minute.

     But the fact is that I am 17 years old and I have my own life style.I am my parents' only child

and my mother says she wants me to have the best possible chance of happiness in the future.

She is always telling me to behave well when I leave home or go out.What's worse,whenever

there is a cold war between my mother and me,my father often keeps silent.I am not only

confused but also hurt.I don't know what to say or what to do to make things right.I think they

are out of fashion and too old to know my inner part.

     To tell the truth,I have packed up my backpack but am still at a loss.

                                                                                                                               Kate
