Time and tide wait no man. My mother is becoming a middle-age woman quietly. She had been busy running after us all the years. My father is very busy every day outside. But the heavy burden falls on my mother's shoulder. Because my school is far from my home, I have to go to school by the train and my mother sees me off at the station every time. I often choose a seat where is close to the window, so I can see her. However, I always can't help run tears from my eyes. All the buildings and people outside the window disappear. I wave gentle to my mother and I look at her till the view of her back disappears. Up to now, even if he is busy, she still does it as usual. The view of my mother's back will never change in my heart.
