After my mobile phone was stolen several days ago,all phone numbers gone. I need some money to buy a new one.But my living expenses is not enough.Difficultly,i got in touch with my mother this eveing.She said she would deposit the money into my bank tomorrow.In fact,i feel very guilty.As my mother said,i cost a lot this term.Although my family has the ability to support me,but i have 21 years of age,i should learn to feed myself.I can understand the meaning of my mother's words,she want me to be independent and without relying on them,i can also have a good life.Many college students are economically dependent on their parents in china.From now on,i will do my best to be self-reliant. So,dear friends,I want to know ,when did you begin to earn a living?or when do you want to be independent?
