阅读下面一则网络帖子,然后按照要求写一篇150词左右的英语短文,作为跟帖。

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 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 and 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.
