Hi! My name's ..... Can I tell you about my lovely house? I live in a house on Tran Quoc Toan street. It's large about 90 square meters and has 3 floors. In front of my house, there is a nice small garden that plants a lot of beautiful flowers and trees. The outside of the wall is light blue. Each room has being decorated with different style and the walls of it have been painted with soft colors to match the curtains. Firstly, on the ground floor, there are 5 rooms that consist of a living room, a dining room, a my parents' room, a garage and a kitchen. My dining room isn't big, but it is enough place for my family to sit and where we spend happy time together. After dinner, we usually watch TV and drink tea in the living room. Next, on the first floor, there are a bedroom, a small living room, an ancestral worship room and a toilet. My room has a bed, a wardrobe and a computer on the desk to do my homework or surf the Internet. Finally, on the second floor, there is a terrace that plants much kinds of vegetables and I can feed birds in cage. Sometimes I also hold a party with my friends or my family at here. Moreover, my neighbors are quite kind, but they are talkative and noisy. When they have some troubles, they often shout loudly and it makes me feel annoyed. I cherish them as well as I love my house. Despite being busy, my mother and I always keep the house clean and tidy. My house is quite old, because it was built about 20 years ago. That is the place I was born and have grown up. I had a lot of wonderful memories in the house, so I love it so much. I think it is the most important and meaningful place for my life.
