I was always busy with my studies and seldom helped my parents with houseworks. Feeling quite sorry for that, and I began to think about how to do to help them. Last Sunday, when my parents went out shopping, I suddenly got idea: why not give the rooms a thoroughly cleaning? First, I collected all the books, newspapers and another things in the rooms and then put it in place. After that, I sweep the floors. At this very moment, my parents came back and were quite surprising to see all the rooms tidy. My mother gave me a hug and I could see satisfaction in his eyes.
