When we enjoy parents'love, we feel very happy. They work so hard for us without any complaints.There is no doubt that we should do something for parents even if we keep busy with our studies.

As for me, I sometimes do chores at home because it is my duty to help my parents. And I like to give my parents a surprise on special days. Last Saturday was Women's Day. I kept thinking of a good idea to make my mum happy. I knew she was really busy every day. She did everything for me but never thought about herself. She even hadn't seen a movie for a long time. When I gave the tickets to her,she was so moved that she couldn't help crying. She hugged me and told me she was the happiest mother in the world.

As students, we seem too busy with studies. However, we should plan time for family activities. Maybe only by planning our studies well can we spend more time doing chores at home or do something to make parents happy.
