Rain is my closefriend. He is the same age as me. He lives with his family at 19 Thai Ha, Dong Da, Ha Noi. I often go to his house to work in group. I think his house is very large. There is a big yard in front of, a a big garden behind the house. His room is very beautiful and comfortable. Do you go to the diningroom? I think you will be amazing about it. It's magnificent. The fan is made by gemstone and almost everything in it are made by gold. If you come to his house, you don't go to the livingroom is a mistake. It's is bigger than I think. There are two TV, not one. This livingroom has an air conditioner, news,.... I think his house is a great house I have never seen before.
