Hello, this year I am twelve years old. I live with my family in a small lovely house on the outskirts of the city. Every day, my mother wakes me up at five thirty. The atmosphere is fresh then. At this time, some other families also wake up, they go to the market, do exercises, prepare the energy for a new day. I always water vegetables and feed chickens in the garden with my father. Then I back to my room, do personal hygiene and get dress, prepare books to go to school. When I get downstairs, my mother is busy with preparing breakfast for the whole family in the kitchen. After eating, my father takes me to school by motorbike because my school is quite far away from my house. At school, I have many friends, they are all very cute and docile. At the breaks, we often play some folk games such as horse jumping, blindfolded goats, box office, ... In addition, I also paripate in some clubs such as book, piano and english club. After school, I and some of my friends often clean the class and study in the group. At night, I help my mother with cooking and then family members gather in the living room to watch the favorite TV channels, share the story of the day. Before going to bed, my father always brings me a glass of milk and check my study. Every day is a great and invaluable gift, the work even seems small but brings me joy and happiness.

In the morning, I wake up at 9 o'clock. By this time, the sky had long since dawned. I look in the mirror and smile, it motivates me for a new day. Then, I brush my teeth and wash my face. After that, I have breakfast. Sometimes, because I get up too late, I don't eat breakfast. At 10 a.m, I do my homework. When I finish my homework, it is 11.30, so I have a lunch. I take a rest at 12.15. I think that. In the afternoon, I do housework with mom and dad. Then we have a dinner. After that, we watch TV. When it is 10 o'clock, we go to bed and sleep.
