I live at home. I really like my house. it is small, but I am not small either. When you enter the house, you see a small kitchen. in the kitchen we cook and eat. I spend a lot of time in the kitchen, because I like to eat. The next room is the entrance hall. in the hallway there is a large closet over the entire wall. there are no windows. through the hallway we go into other rooms. our room is very large. there is a large sofa. the hall is very bright because there are many windows. there are many different colors in the room. The room of my parents and sister is also large. a large TV hangs to the room, it hangs above a large soft bed and there is a bedside table to the right of the bed. and in the second half of the room is my sister’s sofa. my room is the smallest. I even like it. To my room there is an extendable sofa, a table and a TV. there is a yard around the house. My mother loves to grow flowers. we have a bathhouse in our yard. and we also have a dog that lives in a booth that dad built. We have a garage for my father’s car and tools. We also store our things there.
