Dear Dad: Hello! I am writing this letter to talk to you about your habits, hoping to give you some inspiration and let you firmly prevent becoming a cancer of your family. First of all, I want you to know that it will not only damage your health and make your financial situation worse and worse, but most importantly, it will have an extremely negative impact on your family's life. It will make our family's life retrogress and reduce our quality of life, which is definitely something you don't want to see. Secondly, it will make children lose trust and dignity and make family relationships tense and fragile. If you don't quit gambling, your family will become more and more alienated and distrustful. I hope you can realize such negative effects and consequences, and use it as a driving force to try to get rid of your new habits. Finally, apply for you to try to get help to overcome this problem. Please think carefully, reflect on your behavior, and find a suitable way to control and cure your gambling addiction in time. I believe that as long as you have the determination and perseverance to change your existing behavior and thinking habits, you will succeed. Dad, I really hope you can quit gambling, change your current habits and let our family have a better future. Thank you for reading this letter and waiting for your reply. I wish you good health and smooth work! Your child, XXX
