Dear Mark, I am very happy to hear that you are earning to stay with my family for a month. We live in a house with four bedrooms. You will have our own bedroom for your stay here. You asked me about our family rules. There are four important ones that we must follow. Firstly, one of the most important rules in my family is that each member of the family is responsible for the housework for example, while my mother is cooking, my father will clean everything around. Secondly, each family member must have dinner together to foster family affection, because during the day my parents have to go work except for Sunday evenings, each person will be able to meet friend, relative. Third, my family will usually get up before 7:30 AM to exercise for about 15 to 30 minutes for better health. Finally, each family member must observe the curfew after 10:00 PM. In spite of a lot of rules, I feel comfortable and safe because I know that my parents want the best things for me. There are not only family rules but also rules for those who live in the house. If you have any questions, please let me know. We will try our best to make you feel comfortable during your stay with us. I hope you enjoy your time here. Chữa lỗi ngữ pháp giúp mình
