Hi there Jack!

  I am always happy to read your articles. I also like what you had written for me today. Please see the following corrections:

Your composition:

My house is located in Suji. It is a kind of apartment complex. Even thoug It's very old, But I like it. Because There are many children, I like children. and It's safty, because There is a private security guards in each building. So I can work in relived mind at the office. There are 3rooms and 1 living room and 1 dining-room. LCD TV, Console game machine and comfortable sofa are located at the dining-room. I like this space. Becuase I can watch TV with relaxed position or play the game with the playstation. I have my private room. There are several furnitures and IT devices such as PC, iPAD. I usually study at the room if I want to study something without my baby or wife's interference. My house is rental. It's very expensive to buy the house in Korea. I have a plan to buy house in three years. I think that I'd better to economize the cost of living to accomplish it. Thank you for reading my articles.
