According to the traditional habit, we have to go home to get together with our family when it is Mid-autumn Festival Day.But ,as a college student, i'm too far to go back home,so, what can i do is just to give a call to my parents to wish them to enjoy themselves.Without their children, do my parents fell alone? As we grow up,we have to leave home to busy with our personal affairs,carrers,we have lesser and lesser time in company with our ageing parents.Maybe,we can't change the situation,but we must remember that:no matter where we are,our parents' hearts are on us,they are eage to know,is everthing well of my children? is them hearthy? is them happy now or not? So no mattre how busy we are, we must leave out some time to give them a call,your sweet voice is the most comfort to him.
