Last weekend, I did something good for my family that made me feel very happy. On Saturday morning, I saw that my mother was very busy with housework. She had to cook, clean, and do the laundry. I decided to help her by cleaning the floor and washing the dishes. At first, I felt a little tired, but when I saw my mother smiling, I knew it was worth it. Later, my father praised me and said I was becoming more responsible. My younger brother also joined me, and together we finished the work quickly. That day, I learned that even small actions can bring joy to the people we love. Helping my family not only made them happy but also made me proud of myself. I will try to do more good deeds like this in the future.

Hi everyone, my name is Phuong Thao. I will introduce my family to you. Our family has 4 people including my father, my mother, my brother and me. My father is an engineer at a construction site near my home. My father is very busy. He usually had to stand outside all day. So he has a tanned skin. However, one day he still spends time playing with me. My mother is a good housewife. Every day I can eat delicious dishes that I cook. Mother takes care of her family very well. Before I go to bed, my mother usually reads me a story. My brother is 12 years old. I often play with him in my free time so my mom can do other things. I love my family very much.
