On the twenty-fifth of April I visited my friend Petrov. He is an engineer. He has got a large family. He is married, and has got three children. His parents live with him. Several years ago Petrov got a flat. Their flat is on the fifth floor of the new house. There are four rooms in the flat: a dining room, two bedrooms, a study, a bathroom and a kitchen. I really like their dining room. It's a big beautiful room. The walls of this room are yellow. Petrov's wife likes flowers very much.There are usually a lot of flowers in their flat. There is a grand piano in the corner of the dining room.Petrov's son Victor likes music and plays the grand piano. There is a sofa on the right of the grand piano, there is a TV set on the left. There are several pictures on the walls.I also like Petrov's study. It's small, but it is very comfortable. There is a desk,a bookcase and two armchairs. There are many books and magazines in the bookcase. There is a telephone in the study. Yesterday I visited Petrov again. We didn't listen to the radio. We watched a new movie on TV. Then we discussed it. At 11 I left and went home.
