5．It feels like every time my mother and I start to have a conversation，it turns into an argument．We talk about something as simple as dinner plans and suddenly，my mother will push the conversation into World War III．She'll complain（抱怨） about my lack of a bright future because I don't plan to be a doctor．And much to her disappointment，I don't want to do any job related to science，either．In fact，when I was pushed to say that I planned to major in English and communications，she nearly had a heart attack．
"Why can't you be like my coworker's son？"she bemoans all the time．Her coworker's son received a four-year scholarship and is now earning 70，000dollars a year as an engineer．I don't know what to answer except that I simply can't be like Mr．Perfect，as I've called the unnamed coworker's son．I can't be like him．I'm the type of person who loves to help out in the community，writes until the sun goes down，and most of all，wants to achieve a career because I love it，not because of fame （名声） or salary．
I understand why my mother is worried about my future major．I've seen my mother
struggle to raise me on her small salary and work long hours．She leaves the house around 6：30am and usually comes home around 5pm or even 6pm．However，I want her to know that by becoming a doctor，it doesn't mean I'll be successful．I'd rather follow my dreams and create my own future．
